Abstract
E
valuation of the labrum and undersurface of the rotator cuff is often limited with conventional MR imaging. This study compared conventional MR imaging with MR arthrography. We believe the accuracy of diagnoses can be improved with the addition of an intra articular injection.
Thirty patients underwent both conventional MR imaging of the shoulder and MR shoulder arthrography for clinically suspected labral or rotator cuff abnormalities. Images obtained before and after contrast administration were studied independently, and without knowledge of clinical findings, by two radiologists for the presence of abnormalities of the glenoid labrum or rotator cuff. Results were correlated with surgical findings in all patients.
MR Athrography 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 MRA, followed by bankert lesion being positive in 7% by conventional MRI Whereas 27 % were proved positive by MRA, ALPSA was negative in 100 % of patients who underwent conventional MRI while 3% positive result was detected by MRA, and finally compared to 3% positive SLAP cases detected by conventional MRI, 7% positive cases were proved by MRA.
In conclusion Our results suggest that MR arthrography enhances the accuracy of MR in the evaluation of the glenoid labrum and rotator cuff tendon.
