Abstract Glenohumeral joint instability is extremely common. With regard to primary anterior shoulder dislocations, the incidence is between 8.2 and 23.9 per 100 000 person-years, with an estimated prevalence of 1.7%. Many imaging methods, including arthrography, CT arthrography, MR arthrography, have been used to image the glenoid labrum and the associated structures of the capsular mechanism. The aim of the study is to prove MR arthrography is the preferred imaging technique for the investigation of patients with shoulder instability. MR arthrography reliably shows subtle lesions of the labroligamentous complex, providing information essential to the surgeon concerning the surgery or arthroscopic repair .Thirty Patients with clinically evident or suspected shoulder impingemint or glenohumeral instability.of both sexes were included , conventional MRI was performed for all patients followed by CT guided intraarticular contrast injection then MRI Arthrography images taken within thirty minutes. Data were collected, revised, coded and entered to the Statistical Package for Social Science (IBM SPSS) version 20.

Abstract Background Vertebral collapse is a common problem due to benign conditions (trauma, infection, osteoporosis) or malignant process. And although the spine is the most common site of bone metastases (39% of bony metastases in patients with primary neoplasms) benign vertebral fractures due to osteopenia occur in one third of cancer patients, making it essential to determine whether the cause of vertebral collapse is benign or malignant. Aim of the Work To establish the role of DWI in differentiating benign from pathologic vertebral fractures using ADC values in comparison with histopathology report /laboratory evaluation and clinical follow-up. Patients and Methods A cross sectional study is approved by the ethics review board of Ain Shams University Hospital (Al Demerdash). All patients provided informed consent for the MR imaging examinations and for inclusion of their data in this analysis. From April 2020 to october 2020, 25 cases with previous imaging with vertebral compression underwent conventional MRI study on the affected region. Diffusion weighted imaging and ADC was added. Results We performed DWI using maximum b-values 600, and quantitative analysis, named apparent diffusion coefficient (ADC). We correlated the ADC number to histopathology, laboratory finding and clinical follow up. In our study there was significant difference (p < 0.04) between DWI of the benign and malignant groups. Also the ADC value showed significant difference <0.001. The mean ADCs of benign VCFs were higher significantly than those of pathological fractures. Conclusion DWI with ADC value was helpful when added to conventional MRI to differentiate benign from pathological (malignant) vertebral compression. It should be a routine sequence in patients with vertebral compression fractures for accurate diagnosis and successful management also can decrease no of biopsies.

Abstract Purpose of this study is: To evaluate the role of diffusion weighted magnetic resonance imaging in differentiation between malignant & benign hepatic focal lesions. Methods The study included 38 patients all of them were with hepatic focal lesions detected by ultrasound (between 20 and 85 years of age) referred from GIT and oncology departments. Each patient included in the study was subjected to full history taking, ultrasonography and conventional MRI sequences, post Gd- DTPA dynamic and Diffusion Weighted imaging as well as ADC value measurement. Technique was performed using a standard 1.5 Tesla unit (Ingenia, Philips). Detailed MRI and laboratory investigations were done. Results The study showed significant results were obtained between ADC values of benign and malignant hepatic focal lesions (p < 0.001). Conclusion We concluded in this study according to the obtained results that DWI sequence together with quantitative ADC values should be used as an essential sequence to supplement the conventional MRI sequences for proper detection and characterization of hepatic focal lesions.

Objective: To describe the posterior labral lesions and labrocapsular abnormalities of the shoulder on sonoarthrography and to compare these findings with MR arthrography results. Methods: 82 shoulders were initially evaluated with ultrasonography and MRI and then were examined with sonoarthrography and MR arthrography following intraarticular injection of diluted gadolinium solution. The ultrasonography images were prospectively evaluated for the presence of posterior labral tear, sublabral cleft, and posterior capsular abnormalities by two radiologists. The diagnostic accuracy of sonoarthrography in the detection of posterior labral tears and posterior labrocapsular variants was compared with that of MR arthrography. Results: In sonoarthrographic examinations of 82 shoulders, 5 and 6 posterior labral tears were identified by Observer 1 and 2, respectively. Moreover, 6 and 7 posterior sublabral clefts, and 2 and 3 posterior synovial folds were identified by Observer 1 and 2, respectively. All the 82 patients were examined with MR arthrography; however, only 14 patients underwent arthroscopic examination. No significant difference was found among the 82 patients with regard to age, gender, and the prevalence of posterior labral tear, posterior labral cleft, and posterior synovial fold (p > 0.05). Interobserver variability showed substantial agreement between the sonoarthrographic and MR arthrographic results of the posterior labrocapsular structures (κ = 0.71, p < 0.05). Conclusion: Posterior labral tears and posterior synovial folds of the shoulder joint can be evaluated non-invasively by sonoarthrography. Advances in knowledge: Variations and pathologies of posterior labrocapsular structures of the glenohumeral joint are relatively uncommon. Direct (MR) arthrography is the gold-standard imaging modality to evaluate of posterior labrocapsular abnormalities of the glenohumeral joint. Sonoarthrography of the glenohumeral joint may be utilized in clinical practice in patients with contraindications to (MRI).
