Comparative Study of MR Imaging in Diagnosis of Shoulder Instability / 实用放射学杂志

Objective To evaluate the diagnostic value of indirect MR arthrography(MRA) and conventional MR for shoulder instability.Methods 24 cases of shoulder instability were retrospectively analyzed.13 patients underwent conventional MR,11 patients underwent indirect MRA.Based on the results of arthroscopic examination,the efficacy of indirect MRA images and conventional MR images in diagnosis of the labrum,the capsule, and the bone structure injury.Results Indirect MRA in diagnosis of labrum tear was signifiantly better than conventional MR(P0.05).Conclusion Indirect MRA is more helpful to diagnose the labrum tear than conventional MR.Further study should be taken for capsule and ligament injury.
