ULTRASONOGRAPHY AND MR ARTHROGRAM IN DETECTION OF SHOULDER JOINT DISORDERS

Background: Ultrasonography and Magnetic Resonance Imaging (MRI) are widely used to detect a lot of the shoulder joint pathologies as rotator cuff, labral, and capsular abnormalities. Objective: to detect role of ultrasonography and MR Arthrogram in detection of shoulder joint disorders in comparison to conventional MRI. Patients and methods: Thirty patients underwent ultrasound examination, conventional MR imaging of the shoulder and MR shoulder arthrography for clinically suspected labral or rotator cuff abnormalities. This study was done at the Radiodiagnosis Department, Al-Azhar University Hospitals during the period between October 2019 and October 2020. Results: MR arthrography was found superior over conventional MRI in its sensitivity regarding specifically labral tears Whereas 0% of patients were found positive by conventional MRI, 10% of patients were detected by magnetic resonance arthrography (MRA), followed by bankert lesion being positive in 7% by conventional MRI, whereas 27% were proved positive by MRA, anterior labrum periosteal sleeve avulsion (ALPSA) was negative in 100% of patients who underwent conventional MRI, 3% positive result was detected by Magnetic Resonance Angiogram (MRA), and finally compared to 3% positive superior labral anterior posterior (SLAP) cases detected by conventional MRI, 7% positive cases were proved by MRA. Conclusion: Ultrasound together with MR arthrography enhanced the accuracy of MR in the evaluation of the glenoid labrum and rotator cuff tendon.
