Glenoid labral tears: prospective evaluation with MRI imaging, MR arthrography, and CT arthrography.

Abstract

MR arthrography and MR imaging both showed labral tears with greater sensitivity than CT arthrography did. MR arthrography was the most sensitive of the three techniques for detecting a detached labral fragment and labral degeneration. Furthermore, MR arthrography afforded the best visualization of the inferior part of the labrum and the inferior glenohumeral ligament. MR imaging and MR arthrography also enabled direct visualization of rotator cuff disease and other unsuspected associated abnormalities.
