Background/aim: To investigate the relationship between sex-related visceral obesity and WHO/ISUP nuclear grade in clear cell renal cell carcinoma (ccRCC). Materials and methods: Between January 2018 and June 2022, 95 patients (56 men and 39 women) with pathologically proven ccRCC who underwent abdominal computed tomography examination were retrospectively examined. The patients were classified into two groups: low- and high-WHO/ISUP nuclear grade ccRCC (n = 58 and n = 37), respectively. Patient height, weight, body mass index (BMI), sex, age, subcutaneous fat area (SFA), visceral fat area (VFA), total fat area (TFA), and percentage of visceral fat (VF%) were recorded for the two groups. Results: No significant differences were found in age, BMI, SFA, or TFA, but VFA and VF% were significantly higher in the high-grade patient group. In males, maximal tumor diameter (MTD) (67.8% sensitivity and 76.9% specificity) had the highest area under the curve (AUC), while in females, VF% (70.0% sensitivity and 73.7% specificity) had the highest AUC. VF% revealed an odds ratio (OR) of 1.09 in females with high-grade ccRCC, and in males, MTD was an independent predictor of ccRCC with an OR of 1.03. Conclusions: Sex-related body fat tissue, including VFA and VF%, could be used for estimating WHO/ISUP nuclear grade in patients with ccRCC, especially in females. [ABSTRACT FROM AUTHOR]

PURPOSE To evaluate the image quality and tumor morphology depiction ability of high resolution (HR) diffusion-weighted imaging (f-DWI) in comparison to conventional DWI (c-DWI) and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) in the primary breast cancer setting. METHODS The f-DWI, c-DWI, and DCE-MRIs of 160 malignant breast masses were evaluated retrospectively by two independent radiologists. Data on image quality [sharpness, distortion, and perceived signal-to-noise ratio (SNR)], apparent diffusion coefficient (ADC) value, lesion size, and tumor morphology (shape, margin, and internal pattern) obtained on f-DWI, c-DWI, and DCE-MRI were compared. Consistency between the readers and imaging methods for morphological parameters was analyzed. RESULTS The ADC values measured on f-DWI were significantly lower than those measured on c-DWI for both readers (P < 0.001 for each), whereas mean lesion size was significantly larger in c-DWI than in f-DWI and DCE-MRI for both readers (P < 0.001 for each). Higher consistency values were obtained for f-DWI compared with c-DWI when correlated with DCE-MRI for each morphological parameter. The least distorted images were obtained using DCE-MRI compared with c-DWI and f-DWI for both readers, whereas the highest distortion scores were obtained using c-DWI. Sharpness and perceived SNR scores were rated as significantly higher for f-DWI and DCE-MRI images compared with c-DWI by both readers (P < 0.001 for all). The concordance between c-DWI and DCE-MRI was fair to slight (k = 0.15 to 0.41), whereas concordance between f-DWI and DCE-MRI was significantly better (k = 0.68 to 0.87) for each reader and for all morphological parameters (P < 0.001). The highest concordance between the readers was achieved in margin assessment (k = 0.87 to 0.89) regardless of the MRI method, followed by shape and internal pattern parameters (k = 0.63 to 0.79). CONCLUSION The results demonstrated that f-DWI produces higher-quality images than c-DWI, enabling the morphological features to be identified in similar detail to that offered by HR DCE-MRI. Accordingly, f-DWI, as a method that highly correlates with DCE in determining the morphological characteristics of breast cancers, seems to have potential in the evaluation of breast tumors in patients for whom the use of contrast media is contraindicated.

Purpose: The main objective of this study is to describe the retrograde guidewire-assisted remodeling technique (REGART), a novel technique, and assess its feasibility, safety, and effectiveness in the recanalization of ostial arterial occlusions without a visible stump in the critical limb ischemia (CLI). Materials and Methods: A retrospective review of 387 patients who underwent endovascular treatment (EVT) for peripheral artery disease between January 2020 and June 2021 was performed. Among these, 23 patients (14 males [60.8%]) with a mean age of 64.2 (range: 55–72) years who underwent REGART were included. Patient demographics, procedural details, and outcomes were noted. Results: The technical success rate was 95.6% (22/23). The angiographic success rate was 86.3% (19/22). The procedure-related complication rate was 21.7% (5/23), with 4 (17.4%) major complications and 1 (4.3%) minor complication. Conclusion: In the CLI, results of this trial suggest that REGART is feasible, effective, and with acceptable safety in the catheterization of occluded artery origins without a visible stump when conventional anterograde and retrograde techniques fail. Thus, the target occluded artery can be recanalized while preserving other arterial origins by minimizing dissection risk through subintimal balloon angioplasty at the bi-trifurcation level.

Background/aim: The aim of the study was to evaluate the relationship between primary tumor type and the effectiveness of microwave ablation (MWA) therapy by comparing the technical and clinical outcomes of MWA in the treatment of colorectal liver metastases (CLM) and noncolorectal liver metastases (NCLM). Materials and methods: Between January 2019 and March 2021, 47 consecutive patients (25 male, 22 female) with a total of 63 unresectable hepatic metastases underwent MWA under ultrasound guidance. The patients were divided into CLM (n = 29) and NCLM (n = 18) groups. Patient demographics, procedural details, and complications were noted. The overall survival (OS) and disease-free survival (DFS) rates were also analyzed. Results: Technical success was 100% in both groups. No major complication was observed. Three minor complications [fatigue (n = 2) and subcutaneous hematoma (n = 1)] were encountered. DFS rates were 88.9%, 71.9%, 64.9%, and 44.0% at 3, 6, 12, and 24-months, respectively, with a mean DFS of 17.4 months (95% CI: 15.1, 19.7). Also, OS rates were 93.7%, 90.0%, 76.8%, and 64.3%, at 3, 6, 12, and 24-months, respectively, with a mean OS of 18.5 months (95% CI: 16.2, 20.7). There was no significant difference in recurrence between the CLM and NCLM groups (p = 0.452). The recurrence rate in liver metastases > 3 cm in size was significantly higher than in metastases ≤ 3 cm in size (p < 0.001). Conclusions: MWA therapy is as effective in the NCLM group as in the CLM group, regardless of histologic type. Metastasis size (>3 cm) was correlated with the recurrence rate in the CLM and NCLM groups. [ABSTRACT FROM AUTHOR]

Background/aim: This study aims to investigate the relationship between gastric wall fat halo sign and potentially associated cardiovascular disease (CVD) in thoracic computed tomography (CT). Materials and methods: Between October 2020 and January 2021, 62 patients with gastric wall fat halo sign and 62 controls were evaluated with thorax CT. Patient's height, weight, body mass index (BMI), sex, age, comorbidities, laboratory parameters, diameters of cardiac axes, aorta and pulmonary artery; aorta and coronary artery calcium scores were recorded for the two groups. Results: No significant differences were found in sex, age, height, body weight or BMI between the two groups (p > 0.124). Patients with gastric wall fat halo sign had significantly larger diameters of the ascending aorta, the descending aorta, the main pulmonary artery, the right and left pulmonary arteries, and the short and long cardiac axes and a higher cardiothoracic ratio (CTR) than the control group (p < 0.001). Additionally, the calcium scores of the ascending, arcus, and descending aortas and the coronary arteries were significantly higher detected in patients group (p < 0.001). Patient group had significantly higher lipid profile, frequencies of diabetes mellitus (DM) and hypertension (HT) than control group (p<0.026). Conclusion: Patients with a gastric wall fat halo may show higher cardiovascular risk because of increased visceral fat tissue, vascular diameters, CTR, heart sizes, presence of DM, HT, increased lipid profile and calcium scores.

Purpose: To establish the nomograms of fetal nasal bone length reported the ethnic differences and relationship between chromosomal abnormalities, between 18m+0-23+6 gestational weeks. Material and Method: In this study, 2653 fetus between 18m+0-23+6 gestational weeks had normal US findings and had not postnatal anomaly were retrospectively evaluated between January 2009 and September 2014. After detailed fetal anomaly scan, biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), femur length (FL), nasal bone (NB) length and mean gestational weeks (GW) of each fetus were recorded. Regression analyses were performed between NB length and GW, BPD, HC, AC and FL. The reference values for 5-10-25-50-75-90-95. percentiles were established for each gestational week. Results: In this study, 27 twin pregnancies were detected in the 2626 pregnant women (age range, 17-46 years; mean age, 30.02 ±5.78 years). There were 159, 214, 528, 599, 563, 583 fetuses and the mean NB lengths were 5.5 ± 0.85, 6.3 ± 0.83, 6.6 ± 0.81, 6.9 ± 1, 7.1 ± 0.86, 7.6 ± 0.89 (minimum 4 mm and maximum 10.1 mm) between 18m+0-23+6 gestational weeks, respectively. NB length was increased linearly consistent with GH, BPD, HC, AC and FL during 18m+0-23+6 gestational weeks. In correlation analysis, the fetal NB length were significantly correlated with GW, BPD, HC, AC and FL (p<0.001). Conclusion: In our study, we established the NB length nomogram in healthy fetuses between 18m+0-23+6 gestational weeks. We think that this reference values can be used for diagnosis of nasal bone hypoplasia in prenatal screening. [ABSTRACT FROM AUTHOR]

Background/aim: This study aimed to investigate the relationship between the iodine concentration (IC) of perigastric fat tissue as assessed by dual-energy computed tomography (DECT) and serosal invasion of gastric cancer. Materials and methods: A total of 41 patients underwent preoperative staging evaluation for gastric cancer using DECT between July 2015 and March 2018. Patients were divided into 2 groups based on pathology results: serosal invasion (stage T4a) and intact serosa (stages T1–T3). Cutoff values, the diagnostic efficacy of IC in the perigastric fat tissue, and the perigastric fat tissue/tumor (P/T) ratio were determined. Results: Among the 41 patients, 22 had stage T4a gastric cancer and 19 patients had gastric cancer with a stage lower than T4a. The mean IC of perigastric fat tissue and the P/T ratio were significantly higher in patients with serosal invasion than in those with intact serosa (P < 0.001). During the arterial phase, the area under the curve (AUC) was 0.915 and 0.854 for the IC of perigastric fat tissue and the P/T ratio, respectively. During the venous phase, the AUC was 0.890 and 0.876 for the IC of perigastric fat tissue and the P/T ratio, respectively. Conclusion: The IC in the perigastric fat tissue seems to be a reliable indicator for serosal invasion of gastric cancer. [ABSTRACT FROM AUTHOR]

Background/aim: This study aimed to investigate the prevalence and association of mesenteric panniculitis (MP) with other diseases and the clinicoradiological features of MP, and to examine computed tomography findings to estimate the presence of malignancy in patients with MP. Materials and methods: Between September 2012 and August 2016, we used a keyword search to identify patients diagnosed with MP. Associated diseases and malignancies of patients were recorded. Cut-off values and diagnostic efficiencies of total MP scores and short and long diameters of the greatest lymph nodes were determined. Results: Out of 22,033 patients, 309 were determined to have MP (prevalence 1.40%); 57.9% of these patients had a malignancy and 42.1% did not have a malignancy. The mean total MP scores and diameters of the greatest lymph nodes were significantly higher in the patients with a malignancy (P < 0.001). AUCs were 0.728, 0.879, and 0.767 for the short diameter, long diameter, and total score, respectively. The diagnostic efficiencies of the long diameter of the greatest lymph nodes were significantly higher than the total MP scores and the short diameter of the greatest nodes. Conclusion: MP is thought to be associated with abdominal and other system malignancies so MP may be a paraneoplastic syndrome in some patients. [ABSTRACT FROM AUTHOR]

Background: To assess the role of DWI in differentiation haemorrhagic ovary infarction from non-haemorrhagic one. Methods: For this prospectively designed study, of 117 female patients who presented with acute lower quadrant pain and underwent MRI for suspicion of ovary torsion, results of only 29 patients (mean age, 24.7; SD, ±5.7; age range, 18--37), with surgical and pathological confirmation of adnexal torsion, were included to the study. All patients underwent DWI after conventional MRI. Quantitative and qualitative analysis of both the torsed and contralateral normal ovary were performed. Results of conventional MRI and DWI were noted. Results: At operation 15 patients were found to have haemorrhagic infarction while 14 had non-haemorrhagic infarction. Of the 29 patients, 17 torsed ovaries could be salvaged in a viable state. We found statistically significant correlation of the ADC values, between haemorrhagic and non-haemorrhagic ovary infarction. The ADC values were significantly lower in patients with haemorrhagic infarction than non-haemorrhagic ones (p < 0.001). Using an ADC threshold of 1.27, the sensitivity of DWI for haemorrhagic infarction was 0.93 and specificity 0.85. Conclusion: DWI may be used with a significant success for the preoperative diagnosis of haemorrhagic infarction. This may be alerting for pre-emptive surgery in avoiding serious complications and preventing irreversible structural damage of the ovary. [ABSTRACT FROM AUTHOR]

Being one of the conditions presenting with patellar pain, Hoffa's syndrome is characterized with inflammation of the fat tissue in the patellar region. In advanced stage, this may lead to transformation of the fibrocartilage tissue and ossification of the infrapatellar fat pad. Some cases can be associated with tumors or tumor-like conditions. In this article, we describe a 72-year-old female case suffering from knee pain for a long time and discuss the end-stage Hoffa's disease and function of the infrapatellar fat pad in the light of literature.
