- Abstract
Although not necessary for the vast majority of ultrasound-guided procedures, intravenous contrast agents can be useful for procedures aimed at lesions that require contrast enhancement to be seen on ultrasonography. Using contrast-enhanced ultrasonography to guide procedures has two drawbacks: first, because enhancement from ultrasound contrast agents is short lived, it is often necessary to plan several injections; second, because the needle is poorly seen on contrast-enhanced ultrasonography, a dual image display format is necessary. Contrast-enhanced ultrasonography can be used for planning and monitoring diagnostic and therapeutic procedures, for guiding the procedures, and for follow-up. Using contrast-enhanced ultrasonography enables better results in both types of procedures; moreover, it can be used within cavities., (Copyright © 2021 SERAM. Published by Elsevier España, S.L.U.

- Abstract
Objectives: Interventional procedures around the knee are widely adopted for treating different musculoskeletal conditions. A panel of experts from the Ultrasound and Interventional Subcommittees of the European Society of Musculoskeletal Radiology (ESSR) reviewed the existing literature to assess the evidence on image-guided musculoskeletal interventional procedures around the knee, with the goal of highlighting some controversies associated with these procedures, specifically the role of imaging guidance, as well as the efficacy of the medications routinely injected., Methods: We report the results of a Delphi-based consensus of 53 experts in musculoskeletal radiology, who reviewed the published literature for evidence on image-guided interventional procedures around the knee to derive a list of pertinent clinical indications., Results: A list of 10 statements about clinical indications of image-guided procedures around the knee was created by a Delphi-based consensus. Only two of them had the highest level of evidence; all of them received 100% consensus., Conclusions: Ultrasonography guidance is strongly recommended for intra-articular and patellar tendinopathy procedures to ensure the precision and efficacy of these treatments. Prospective randomized studies remain warranted to better understand the role of imaging guidance and assess some of the medications used for interventional procedures around the knee., Key Points: • A list of 10 evidence-based statements on clinical indications of image-guided interventional procedures around the knee was produced by an expert panel of the ESSR. • Strong consensus with 100% agreement was obtained for all statements. • Two statements reached the highest level of evidence, allowing us to strongly recommend the use of ultrasonography to guide intra-articular and patellar tendon procedures to ensure higher accuracy and efficacy of these treatments., (© 2021.

- Abstract
Objectives: To perform a Delphi-based consensus on published evidence on image-guided interventional procedures for peripheral nerves of the lower limb (excluding Morton's neuroma) and provide clinical indications., Methods: We report the results of a Delphi-based consensus of 53 experts from the European Society of Musculoskeletal Radiology who reviewed the published literature for evidence on image-guided interventional procedures offered around peripheral nerves in the lower limb (excluding Morton's neuroma) to derive their clinical indications. Experts drafted a list of statements and graded them according to the Oxford Centre for evidence-based medicine levels of evidence. Consensus was considered strong when > 95% of experts agreed with the statement or broad when > 80% but < 95% agreed. The results of the Delphi-based consensus were used to write the paper., Results: Nine statements on image-guided interventional procedures for peripheral nerves of the lower limb have been drafted. All of them received strong consensus. Image-guided pudendal nerve block is safe, effective, and well tolerated with few complications. US-guided perisciatic injection of anesthetic provides good symptom relief in patients with piriformis syndrome; however, the addition of corticosteroids to local anesthetics still has an unclear role. US-guided lateral femoral cutaneous nerve block can be used to provide effective post-operative regional analgesia., Conclusion: Despite the promising results reported by published papers on image-guided interventional procedures for peripheral nerves of the lower limb, there is still a lack of evidence on the efficacy of most procedures., Key Points: • Image-guided pudendal nerve block is safe, effective, and well tolerated with few complications. • US-guided perisciatic injection of anesthetic provides good symptom relief in patients with piriformis syndrome; however, the addition of corticosteroids to local anesthetics still has an unclear role. • US-guided lateral femoral cutaneous nerve block can be used to provide effective post-operative regional analgesia. The volume of local anesthetic affects the size of the blocked sensory area., (© 2021. The Author(s).)

- Abstract
Objectives: Clarity regarding accuracy and effectiveness for interventional procedures around the foot and ankle is lacking. Consequently, a board of 53 members of the Ultrasound and Interventional Subcommittees of the European Society of Musculoskeletal Radiology (ESSR) reviewed the published literature to evaluate the evidence on image-guided musculoskeletal interventional procedures around this anatomical region., Methods: We report the results of a Delphi-based consensus of 53 experts from the European Society of Musculoskeletal Radiology who reviewed the published literature for evidence on image-guided interventional procedures offered around foot and ankle in order to derive their clinical indications. Experts drafted a list of statements and graded them according to the Oxford Centre for evidence-based medicine levels of evidence. Consensus was considered strong when > 95% of experts agreed with the statement or broad when > 80% but < 95% agreed. The results of the Delphi-based consensus were used to write the paper that was shared with all panel members for final approval., Results: A list of 16 evidence-based statements on clinical indications for image-guided musculoskeletal interventional procedures in the foot and ankle were drafted after a literature review. The highest level of evidence was reported for four statements, all receiving 100% agreement., Conclusion: According to this consensus, image-guided interventions should not be considered a first-level approach for treating Achilles tendinopathy, while ultrasonography guidance is strongly recommended to improve the efficacy of interventional procedures for plantar fasciitis and Morton's neuroma, particularly using platelet-rich plasma and corticosteroids, respectively., Key Points: • The expert panel of the ESSR listed 16 evidence-based statements on clinical indications of image-guided musculoskeletal interventional procedures in the foot and ankle. • Strong consensus was obtained for all statements. • The highest level of evidence was reached by four statements concerning the effectiveness of US-guided injections of corticosteroid for Morton's neuroma and PRP for plantar fasciitis., (© 2021.

- Abstract
Objectives: Image-guided musculoskeletal interventional procedures around the hip are widely used in daily clinical practice. The need for clarity concerning the actual added value of imaging guidance and types of medications to be offered led the Ultrasound and the Interventional Subcommittees of the European Society of Musculoskeletal Radiology (ESSR) to promote, with the support of its Research Committee, a collaborative project to review the published literature on image-guided musculoskeletal interventional procedures in the lower limb in order to derive a list of clinical indications., Methods: In this article, we report the results of a Delphi-based consensus of 53 experts who reviewed the published literature for evidence on image-guided interventional procedures offered in the joint and soft tissues around the hip in order of their clinical indications., Results: Ten statements concerning image-guided treatment procedures around the hip have been collected by the panel of ESSR experts., Conclusions: This work highlighted that there is still low evidence in the existing literature on some of these interventional procedures. Further large prospective randomized trials are essential to better confirm the benefits and objectively clarify the role of imaging to guide musculoskeletal interventional procedures around the hip., Key Points: • Expert consensus produced a list of 10 evidence-based statements on clinical indications of image-guided interventional procedures around the hip. • The highest level of evidence was only reached for one statement. • Strong consensus was obtained for all statements., (© 2021.

- Abstract
US-guided foreign body removal is a nonsurgical highly effective technique used to manage symptomatic foreign bodies and should be considered as a first-line treatment procedure. The authors describe a technique used for US detection and US-guided removal of various types of foreign bodies and discuss the efficacy of the procedure. Soft-tissue foreign bodies can result from accidents or medical procedures, and they are a relatively frequent reason that patients obtain medical consultation. Foreign body objects include vegetal, metallic, and glass objects, and they may be medical devices such as contraceptive implants. Frequently, physical examination is not sensitive enough to detect the presence of a foreign body, and imaging is necessary. US has demonstrated high specificity and moderate sensitivity for detection of foreign bodies, and it has the advantage of depicting all types of materials. Thus, US has become the imaging technique of choice for evaluating suspected foreign bodies. Although the US features are dependent on the foreign body type and shape, all foreign bodies are echogenic and frequently demonstrate posterior shadowing or reverberation artifact. US has an added value in that it can be used to plan the removal of a foreign body and also guide the entire percutaneous removal procedure. Through a small incision in the skin, just wide enough for the foreign body to pass through, surgical forceps can be inserted and directed under US guidance to reach the foreign body and remove it. The effectiveness of US-guided percutaneous removal can be near 100%. Online supplemental material is available for this article.

- Abstract
Background: Although image-guided interventional procedures of the elbow and wrist are routinely performed, there is poor evidence in the literature concerning such treatments. Our aim was to perform a Delphi-based consensus on published evidence on image-guided interventional procedures around the elbow and wrist and provide clinical indications on this topic., Methods: A board of 45 experts in image-guided interventional musculoskeletal procedures from the European Society of Musculoskeletal Radiology were involved in this Delphi-based consensus study. All panelists reviewed and scored published papers on image-guided interventional procedures around the elbow and wrist updated to September 2018 according to the Oxford Centre for Evidence-based Medicine levels of evidence. Consensus on statements drafted by the panelists about clinical indications was considered as "strong" when more than 95% of panelists agreed and as "broad" if more than 80% agreed., Results: Eighteen statements were drafted, 12 about tendon procedures and 6 about intra-articular procedures. Only statement #15 reached the highest level of evidence (ultrasound-guided steroid wrist injections result in greater pain reduction and greater likelihood of attaining clinically important improvement). Seventeen statements received strong consensus (94%), while one received broad consensus (6%)., Conclusions: There is still poor evidence in published papers on image-guided interventional procedures around the elbow and wrist. A strong consensus has been achieved in 17/18 (94%) statements provided by the panel on clinical indications. Large prospective randomized trials are needed to better define the role of these procedures in clinical practice., Key Points: • The panel provided 18 evidence-based statements on clinical indications of image-guided interventional procedures around the elbow and wrist. • Only statement #15 reached the highest level of evidence: ultrasound-guided steroid wrist injections result in greater pain reduction and greater likelihood of attaining clinically important improvement. • Seventeen statements received strong consensus (94%), while broad consensus was obtained by 1 statement (6%).

- Abstract
Background: Image-guided interventional procedures of the nerves are commonly performed by physicians from different medical specialties, although there is a lack of clinical indications for these types of procedures. This Delphi-based consensus provided a list of indications on image-guided interventional procedures for nerves of the upper limb based on updated published evidence., Methods: An expert panel of 45 members of the Ultrasound and Interventional Subcommittees of the ESSR participated in this Delphi-based consensus study. After revision of the published papers on image-guided interventional procedures for nerves of the upper limb updated to September 2018, the experts drafted a list of statements according to the Oxford Centre for evidence-based medicine levels of evidence. Consensus on statements regarding clinical indications was considered as strong when more than 95% of experts agreed, and broad if more than 80% agreed., Results: Ten statements were drafted on procedures for nerves of the upper limb. Only two statements reached the highest level of evidence (ultrasound guidance is a safe and effective method for brachial plexus block; ultrasound-guided non-surgical approaches are safe and effective methods to treat carpal tunnel syndrome in the short term, but there is sparse evidence on the mid- and long-term effectiveness of these interventions). Strong consensus was obtained on 6/10 statements (60%), while 4/10 statements reached broad consensus (40%)., Conclusions: This Delphi-based consensus study reported poor evidence on image-guided interventional procedures for nerves of the upper limb. Sixty percent of statements on clinical indications provided by the expert board reached a strong consensus., Key Points: • An expert panel of the ESSR provided 10 evidence-based statements on clinical indications for image-guided interventional procedures for nerves of the upper limb • Two statements reached the highest level of evidence • Strong consensus was obtained on 6/10 statements (60%), while 4/10 statements reached broad consensus (40%).

- Abstract
Background: Image-guided interventional procedures around the shoulder are commonly performed in clinical practice, although evidence regarding their effectiveness is scarce. We report the results of a Delphi method review of evidence on literature published on image-guided interventional procedures around the shoulder with a list of clinical indications., Methods: Forty-five experts in image-guided musculoskeletal procedures from the ESSR participated in a consensus study using the Delphic method. Peer-reviewed papers regarding interventional procedures around the shoulder up to September 2018 were scored according to the Oxford Centre for Evidence-based Medicine levels of evidence. Statements on clinical indications were constructed. Consensus was considered as strong if more than 95% of experts agreed and as broad if more than 80% agreed., Results: A total of 20 statements were drafted, and 5 reached the highest level of evidence. There were 10 statements about tendon procedures, 6 about intra-articular procedures, and 4 about intrabursal injections. Strong consensus was obtained in 16 of them (80%), while 4 received broad consensus (20%)., Conclusions: Literature evidence on image-guided interventional procedures around the shoulder is limited. A strong consensus has been reached for 80% of statements. The ESSR recommends further research to potentially influence treatment options, patient outcomes, and social impact., Key Points: • Expert consensus produced a list of 20 evidence-based statements on clinical indications of image-guided interventional procedures around the shoulder. • The highest level of evidence was reached for five statements. • Strong consensus was obtained for 16 statements (80%), while 4 received broad consensus (20%).

- Abstract
Objective: To evaluate the performance of core-needle biopsy (CNB) in thyroid using a cohort of patients in which it was used as first choice., Methods: Our institutional review board approved this retrospective study. We reviewed all CNB performed in our center over a period of 11 years. Ultrasound-guided CNBs were performed using a spring-loaded 18-gauge biopsy needle. We used a classification with four diagnostic categories for CNB results: insufficient, benign, follicular lesion (indeterminate), and malignant. Final diagnosis was based on surgical diagnosis or follow-up of at least 2 years in non-operated patients., Results: The study included 4412 CNB in 4112 nodules of 3768 patients, 300 of them repeated biopsies. Results were 148 insufficient (3.4%), 3706 benign (84%), 278 follicular lesions (6.3%), and 280 malignant (6.3%). Considering follicular lesion and malignancy CNB results as positive (both lead to the recommendation of surgery) sensitivity was 96% (CI 93.2-97.8) and specificity 93.7% (CI 92.9-94.5). Predictive positive value for a follicular lesion diagnosis was 12.2% and for a malignancy diagnosis, 98.6%. CNB likelihood ratio for malignancy of a malignant diagnosis was 841.9 (CI 315.8-2313.3), of a malignant/follicular lesion diagnosis was 23.4 (CI 20.1-27.3), and of a benign diagnosis was 0.04 (CI 0.02-0.07). Repeated CNB in 53 insufficient biopsies obtained 50 diagnostic results. Minor complications occurred in 2.2% of CNB, and major in four procedures (0.09%)., Conclusions: CNB in thyroid nodules is accurate and has few complications and a low rate of non-diagnostic and indeterminate diagnoses. It can be an alternative method when FNAC has poor performance. Repeating biopsy is useful after non-diagnostic biopsies., Key Points: • Core-needle biopsy of thyroid has a low ratio non-diagnostic and indeterminate results. • Core-needle biopsy results are highly reliable, especially benign results. • Complication rate of core-needle biopsy of thyroid is low.

- Abstract
Objectives: To review the diagnostic accuracy of ultrasound-guided core-needle biopsy (CNB) in the diagnosis of salivary gland tumours (SGT)., Methods: Retrospective, institutional review board approved, analysis of the CNB of SGT performed at our centre in 8 years. We used an automatic 18-G spring-loaded device. The final diagnosis was based on surgery in the cases that were operated on, and on clinical evolution and biopsy findings in the rest., Results: Four hundred and nine biopsies were performed in 381 patients (ages, 2-97 years; mean, 55.9). There were two minor complications. Biopsy was diagnostic in 98.3%. There were eight false negatives. The diagnostic values for malignancy were: sensitivity 89.6%, specificity 100%, positive predictive value (PPV) 100% and negative predictive value (NPV) 98%. For the detection of neoplasms were: sensitivity 98.7%, specificity 99%, PPV 99.7% and VPN 96.1%., Conclusions: Accuracy of CNB in SGT is very high, with a very high sensitivity and an absolutely reliable diagnosis of malignancy. Complication rate is very low. It should be considered the technique of choice when a STG is detected. Normal tissue results warrant repeating biopsy., Key Points: • Ultrasound-guided core-biopsy is the technique of choice in salivary glands nodules • Sensitivity, specificity for detecting neoplasms (which should be resected) are around 99% • Diagnosis of malignancy in core-biopsy is absolutely reliable • A CNB result of "normal tissue", however, warrants repeating the biopsy • Complication rate is very low.

- Abstract
Objectives: To analyze the diagnostic accuracy of ultrasound-guided core-needle biopsy (CNB) of thyroid nodules., Methods: Of 3517 CNBs performed using an 18G spring-loaded device in one institution, we retrospectively reviewed 676 nodules in 629 consecutive patients who underwent surgery. CNB and pathological examination were compared. CNB diagnosis was standardized in four categories: insufficient (I), benign (B), follicular lesion (FOL), and malignant (M). Main outcome measures were predictive positive values (PPV), false positives (FP), and false negatives (FN)., Results: CNB showed a low rate of insufficient and FOL diagnoses (5.8 % and 4.5 %). On surgery, there were eight FNs in 374 benign CNBs and three FPs in 148 malignant CNBs. The 154 nodules classified as FOL in CNB included, at surgery, 122 neoplasms; 28 of them malignant. PPV for malignancy of a malignant CNB was 98 %, and for a CNB diagnosis of FOL 18.2 %. Sensitivity for malignancy if CNB of FOL and M are considered positive was 95.6. Only one major complication was observed., Conclusions: CNB is reliable, safe, and accurate to evaluate thyroid nodules and can be an alternative technique to FNA. It has low rate of non-diagnostic and undetermined cases, with high sensitivity and PPV., Key Points: Thyroid core-needle biopsy (CNB) has high sensitivity and PPV. Pitfalls of CNB are rare. Pitfalls are due to cystic cancer, histological heterogeneity, and mistakes in analysis. CNB is a reliable, safe, and accurate method to approach thyroid nodules. CNB can be used primarily or after insufficient or indeterminate FNA.

López JI, Zabala R, and Del Cura JL
- Abstract
Background: Thyroid core biopsies obtained with ultrasound (US)-guided needles are an alternative to conventional fine-needle aspiration and, according to various authors, have greater sensitivity and specificity. The technique is inexpensive, rapid and reliable with a low rate of complications, similar to conventional fine-needle aspiration procedures., Objectives: This paper critically reviews the methodology for obtaining samples and processing them in the pathology laboratory., Methods: Accumulated experience with 1,065 cases of US-guided core biopsy of the thyroid gland in a 15-year period., Results: US-guided core biopsy is a useful, inexpensive and safe method in the histological diagnosis of thyroid gland pathology. Thyroid samples obtained this way are not a substitute for fine-needle aspiration cytology. Indeed, some authors assert that the best results are obtained by combining the two approaches, the methods being complementary., Conclusions: To take best advantage of the findings from these techniques, pathologists must know which types of diagnoses can be made and the fundamentals of how and, lastly, what cannot be diagnosed and the reasons why. Best results are obtained with a multidisciplinary approach in a hospital committee composed of endocrinologists, surgeons, radiologists and pathologists, who analyse and provide a background on each case.

- Abstract
Ultrasonography is the most appropriate tool for interventional procedures in the musculoskeletal system when the lesion is visible on ultrasonography. Procedures performed under ultrasonographic guidance include: taking biopsies; draining abscesses; bursitis; hematomas or muscle tears; treating cystic lesions; diagnostic or therapeutic arthrocentesis; injecting substances into joints or lesions; aspirating calcium deposits and extracting foreign bodies. Although some of these procedures are often carried out without imaging guidance, ultrasonographic guidance improves their efficacy. Drainage can be performed with catheters or needles and makes it possible to avoid more aggressive treatments in most cases. Urokinase is useful for draining hematomas or fibrinous collections. Injecting corticoids is useful in the treatment of synovial cysts, Baker's cyst, tendinitis, and non-infective arthritis. Calcifying tendinitis of the shoulder can be treated effectively with percutaneous calcium lavage., (Copyright © 2010 SERAM. Published by Elsevier Espana. All rights reserved.)

- Abstract
US has important advantages in guiding interventional procedures: it is economical and widely available, it does not use ionizing radiation, and it requires less time than other techniques. US guidance can be provided using devices adapted to probes or using the freehand technique (holding the needle in one hand and the probe in the other). US-guided procedures require careful planning, adequate hemostasis or a directly compressible puncture site, the patient's informed consent, and appropriate measures to ensure asepsis and anesthesia. The technique involves introducing the needle or catheter through the plane of the US slice. The advance of the needle is controlled in real time. High resolution linear probes are ideal for interventional procedures in superficial tissues, but 3.5 MHz probes are required for procedures in deep tissues. The most common procedures include biopsies, drainages, and percutaneous injections. Biopsies can be carried out using fine needles to obtain material for cytological study (fine-needle aspiration cytology) or using large needles to obtain specimens for histologic study (core biopsy). Core biopsy is more sensitive and more specific, and it has a low rate of complications. Drainage almost always involves placing a catheter in a fluid collection; it can be done using the Seldinger techniques, trocars, or pleural catheters. US-guided percutaneous injections can be used to inject substances into infectious lesions, tumors, or nerve plexuses, and they are especially useful in musculoskeletal disease., (Copyright © 2009 SERAM.

- Abstract
Background: Radiofrequency ablation (RFA) is a minimally aggressive, therapeutic alternative for renal tumors. It can be an alternative to nephrectomy in patients with previous nephrectomy, bilateral tumors, von Hippel-Lindau disease, or small renal carcinomas and in those with contraindications for surgery., Objective: To assess the effectiveness of the treatment of renal tumors by RFA in the short and medium term and to identify the possible complications and the factors that determine therapeutic success., Design, Setting, and Participants: A retrospective review of patients with renal tumors treated with RFA between May 2005 and December 2008 was performed in a tertiary academic hospital. Patients were selected among those with previous nephrectomy, bilateral neoplasms, von Hippel-Lindau disease, surgical risk, comorbidity, advanced age, or patient's refusal to surgery. Tumors with evidence of extrarenal extension were excluded. Patients were followed up for 10-50 mo using computed tomography and magnetic resonance imaging., Intervention: Ultrasound-guided RFA was performed on 65 tumors (range: 1.2-5.3 cm) of 58 patients using multitined electrodes., Measurements: Incomplete ablation rate, therapeutic success rate, and complications rate., Results and Limitations: Therapeutic success was achieved in 59 of 65 tumors (91%): 53 in a single session, 5 in two sessions, and 1 in three sessions. A significant relationship was observed between size and growth pattern of the tumor and both therapeutic success and incomplete ablation rates. Therapeutic success in tumors >5 cm was 60%. Complications were detected in 10 patients (13%); 5% were considered major complications. Limitations include the lack of pathologic studies to confirm a complete ablation and the lack of a control group to compare with the results of those who underwent nephrectomy., Conclusions: RFA is safe and effective in renal tumors. Corticomedullary lesions and tumors >3 cm have greater possibility of incomplete ablation. In tumors >5 cm, RFA has a significant failure rate., (2009 European Association of Urology.

- Abstract
Calcific tendinitis is caused by the pathologic deposition of calcium hydroxyapatite crystals in tendons and is a common cause of joint pain. The disease typically affects the shoulder and hip, with characteristic imaging findings; however, any joint can be involved. Occasionally, calcific tendinitis can mimic aggressive disorders, such as infection and neoplasm, especially on magnetic resonance imaging. Radiologists should be familiar with the imaging findings to distinguish calcific tendinitis from more aggressive processes. Image-guided percutaneous needle aspiration and steroid injection of calcific tendinitis are useful techniques performed by the radiologist for the treatment of symptomatic cases. Familiarity with these procedures and their imaging appearance is an important aspect in the management of this common disease.

- Abstract
Ultrasound allows the exploration of most of the musculoskeletal system, including lytic bone lesions. Its flexibility, availability, and low cost make it the best tool to guide interventional therapeutic procedures in any musculoskeletal system lesion visible on ultrasound. These techniques include drainages of abscesses, bursitis, hematomas or muscular strains, treatment of cystic lesions (ganglions, Baker's cysts), arthrocentesis, injection of substances in joints and soft tissues, and aspiration of calcific tendinitis. Although the puncture of joints for arthrocentesis and injection of substances are performed by clinicians using palpation, the use of ultrasound guidance improves the effectiveness of the technique especially for small or poorly accessible lesions and joints and for obese patients. Drainage can be performed using catheters or needles and can avoid a more aggressive approach most of the time. Intracavitary urokinase helps when the aim is to drain clotted hematomas or fibrinous collections. Injection of corticoids is useful in the treatment of ganglia, Baker's cysts, tendinitis, and noninfected arthritis. Calcific tendinitis of the shoulder can be effectively treated using percutaneous "lavage" with lidocaine. Calcifications usually disappear and symptoms improve in nearly 90% of the cases within a year. Most of these techniques are low cost and require only a moderate skill. Ultrasound-guided procedures are useful tools to effectively treat some diseases of the musculoskeletal system and should be routine in any imaging department.

- Abstract
To assess the reliability of indirect computed tomography venography (CTV) in the detection of deep venous thrombosis (DVT) in patients with clinical suspicion of pulmonary embolism (PE). 235 consecutive patients with suspicion of PE underwent an imaging protocol composed of a CT pulmonary angiography (CTPA), a CTV and an ultrasound study of the deep venous system, which was considered the "gold standard." Sensitivity, specificity, and predictive values were calculated for CTV. ith CTV, 30 (12.8%) cases of DVT were detected, 9 (3.8%) of them without pulmonary embolism in CTPA, increasing the diagnosis of thromboembolic disease in 3.8%. However, six of these nine diagnoses were false positives, and CTV missed six cases of DVT. CTV rendered a sensitivity of 58.8%, specificity of 95.0%, a positive predictive value of 66.7%, and a negative predictive value of 93.2%. In patients with clinical suspicion of pulmonary embolism, ultrasound is preferred to CTV for the detection of DVT.

- Abstract
Objective: The purpose of our study was to evaluate the short- and long-term effectiveness of sonographically guided percutaneous needle aspiration and lavage in calcific tendinitis of the shoulder and to study the progress of calcifications and symptoms in the first year after treatment., Materials and Methods: Symptoms and radiologic findings after percutaneous aspiration of calcific tendinitis were prospectively evaluated in the short and the long term using a shoulder pain and disability index, evaluation of shoulder motion, and a survey of the self-perception by the patients regarding the progress of their disease., Results: Sixty-seven consecutive shoulders were treated. A significant improvement was seen in shoulder motion, pain, and disability in the short term and in the long term (p < 0.0001). One year after treatment, 91% of shoulders had substantially or completely improved, 64% had perfect motion, and calcifications on radiography had resolved completely or nearly completely in 89%. A transitory recurrence was observed approximately 15 weeks after treatment in 44.3% of shoulders that improved., Conclusion: Percutaneous needle aspiration and lavage is effective in the short term and in the long term in calcific tendinitis of the shoulder, with results similar to or better than those published for other techniques, and it is only slightly invasive and painful. Progress after treatment may include a transitory period of recurrence of the pain.

- Abstract
Core biopsy has not traditionally been recommended in the study of spleen nodules due to the supposed fragility of this organ leading to a high risk of post-core biopsy complications. A total of 13 patients who presented solid spleen nodules, diffuse splenomegaly, or both on imaging studies (CT, MR, US) were biopsied under ultrasound control with 18G BioPince needles. Cytological (imprints and cytocentrifugates) and histological material were obtained for diagnosis in every case. Malignant lymphomas were the most commonly found pathology (four diffuse large B-cell lymphomas, two follicular lymphomas, one Hodgkin's disease, one B-cell lymphoma, NOS). In addition, there was one littoral-cell angioma, one well-differentiated neuroendocrine carcinoma, metastatic, and one haemangioma. The remaining two cases showed congestive features, and supposed spleen involvement by lymphoma in one of them was ruled out. On follow up, there were no complications related to the core biopsy. Splenectomy was performed in six cases, two diagnostic and four therapeutic. We conclude that core biopsy is a safe and efficient method in the diagnosis of spleen nodules that could be considered in the routine diagnostic algorithm of these lesions.

- Abstract
Objective: The objectives of our study were to investigate differences in Doppler sonography features between benign and malignant breast lesions and between malignant lesions with different prognostic factors and to propose diagnostic criteria for Doppler sonography of breast lesions., Subjects and Methods: We performed power and duplex Doppler sonography examinations in 826 breast lesions scheduled for sonographically guided core needle biopsy. Lesion vascularity, pulsatility index (PI), and resistive index (RI) of the vessels detected were analyzed and correlated with histologic results., Results: Color flow was more frequently seen in malignant (237/348 lesions, 68%) than in benign (171/478, 36%) lesions (p < 0.001). However, sensitivity, specificity, and positive and negative predictive values for this sign were low (68%, 64%, 58%, and 73%, respectively). The RI and PI values were significantly higher (p < 0.001) in cancers. Although an overlap in these values between benign and malignant lesions was observed, all but one nodule with an RI of greater than 0.99 (those with null or inverted diastolic flow) or a PI of greater than 4 were malignant. No significant relationship was found between PI, RI, or flow visualization on power Doppler sonography and tumor grade or lymph node involvement in cancers., Conclusion: Flow visualization on power Doppler sonography indicates a higher possibility of malignancy but is not useful as the main sign for malignancy. However, any lesion with a vessel that has an RI value greater than 0.99 or a PI value greater than 4 within it must be considered as probably malignant regardless of any other sonography sign present. Doppler findings are not useful to predict tumor grade or lymph node involvement.

- Abstract
Ultrasound-guided needle biopsy is a safe and efficient diagnostic method increasingly used in the initial approach to superficial and deep musculoskeletal tumours. However, so far no general consensus has been reached regarding its reliability. During a 6-year period (1999-2004), biopsies were taken from 188 patients (100 females, 88 males; age average 55.8 years) with musculoskeletal tumours under ultrasound guidance using 18G BioPince or 14G ProMag 2.2 true-cut type needles. Cytological (imprints and cytocentrifugates) and histological material was obtained for diagnosis in every case. The lower extremity (59 cases) and the abdominal wall (29 cases) were the most commonly affected sites. Benign/reactive tumours (77 cases), metastatic epithelial malignancies (40 cases), and sarcomas (36 cases) were most frequently diagnosed. In 180 (95.75%) cases, core needle results were concordant with the definitive diagnosis (97 true positives and 83 true negatives). Relevant diagnostic discordance was seen in 8 (4.25%) cases (8 false negatives and 0 false positives). Sensitivity, specificity and positive and negative predictive values were 92%, 100%, 100%, and 91%, respectively. Ultrasound-guided core biopsy is thus a useful method in the initial approach to musculoskeletal tumours that allows correct patient management in the vast majority of cases.
