Objective and purpose: The aim of this study was to determine the acromio-humeral, coraco-humeral, and coraco-clavicular distances with magnetic resonance imaging (MRI) in the diagnosis of shoulder impingement syndrome. Subjects and methods: All the acromiohumeral, coraco-humeral, and coraco-clavicular intervals of all patients were reviewed retrospectively. A total of 132 shoulders (76 right and 56 left shoulders) with impingement syndrome (40 males and 92 females, with 79 cases surgically confirmed and the remaining 53 cases clinically and radiologically suspected) and 40 control group patients were included. Statistical correlation of this research was assessed by Fisher's Exact t test and Pearson chi-square test-correlation coefficients. Results: In the correlation of average acromio-humeral, coracohumeral, and coraco-lavicular intervals (AHI, CHI, and CCI, respectively), there were significant statistical differences between patient and control groups; all the intervals were found to be higher in the control group. A moderate positive relation between average AHI and CHI, between AHI and CCI, and between CCI and CHI has been found. All intervals in the patient group increase or decrease dependently on each other. No proper cut-off values were determined using a receiver operating characteristic curve for all intervals between patient and control groups. Conclusion: Acromio-humeral, coraco-humeral, and coraco-clavicular intervals were extremely lower in the shoulder impingement syndrome and had significant importance in the diagnosis of subacromial and subcoracoid impingements.

Abstract: Tuberculosis (TB) of the breast is a rare disease especially seen in underdeveloped countries. Special care is needed and precise diagnosis is essential since it may mimic carcinoma clinically and radiologically. The breast may become a major site of extra pulmonary TB with the increasing incidence of TB and spread of AIDS worldwide. Here, we report a 45-year-old woman who had been diagnosed as primary breast tuberculosis and treated with anti-tuberculosis therapy 8 years ago and currently diagnosed as recurrent tuberculosis presenting with similar symptoms in her left breast possibly due to insufficient treatment. In this case report, we aimed to present the radiological and clinical findings of breast tuberculosis and emphasize the importance of adequate treatment. [Copyright &y& Elsevier]

Abstract: In this report, we describe fast contrast-enhanced magnetic resonance venography (CE-MRV) findings in orbital varix. Although 2D-TOF MR angiography may allow the demonstration of low flow in venous vascular structures, orbital varices may not be detected as they contain stagnant blood and appear as soft tissue masses. The CE-MRV is faster, which allow to the Valsalva maneuver and can demonstrate stagnant blood with contrast enhancement. To the best of our knowledge, findings of CE-MRV in orbital varix has not been previously reported. [Copyright &y& Elsevier]

Abstract: Purpose: Performance of proton magnetic resonance spectroscopy (H-MRS) and apparent diffusion coefficient (ADC) values in the diagnosis of malignant thyroid nodules. Method: In a retrospective study with malignant nodules of 14 patients, H-MRS and diffusion-weighted MR imaging (DWI) were performed. Choline (Cho) peak, Cho/creatine (Cr) ratio, and ADC values of malignant nodules were correlated with the five benign nodules and four normal-appearing thyroid lobe parenchymata. The gold standard reference was fine needle aspiration biopsy and histopathology. Results: At echo time 40–144-ms acquisitions, average Cho/Cr ratio for the malignant nodules was 2.95±1.54–5.30±2.38, cutoff values were >0.805 and >1.225, and ADC values were 0.06±0.02. Conclusion: H-MRS acquisitions, DWI, and ADC mapping give diagnostic data about the nature of the nodules. [Copyright &y& Elsevier]

Abstract: The aim of this prospective study was to determine and compare the orbital Doppler ultrasonography parameters of patients with Behçet''s disease (with or without ocular involvement) with those of healthy subjects. We evaluated ophthalmic artery (OA), central retinal artery, posterior ciliary artery (PCA), central retinal vein, and superior ophthalmic vein (SOV) flow velocities and resistance indices (RIs). Detection of the decreased flow velocities in the OA and SOV and the increased RI in the OA and PCA might allow the identification of active period of patients with Behçet''s disease.

A prospective comparison of different direct and indirect Doppler parameters with angiography was performed to determine the most useful Doppler parameters and threshold values for the detection of significant (≥60%) renal artery stenosis (RAS). The best combination of parameters was found to be the use of direct parameters of peak systolic velocity (PSV) greater than 180 or 200 cm/s and renal aortic ratio (RAR) greater than 3.0 with a sensitivity and specificity at 92% and 88%, respectively.
