Abstract
Background: MR arthrography in the abduction and external rotation (ABER) position has been demonstrated to enhance the diagnostic ratio of anterior labro-ligamentous complex tears. Meanwhile, the diagnostic and discriminatory rates of MR arthrography in this position in various types of the antero-inferior labro-ligamentous lesions have not been completely discovered. Aim: This study aimed to perform comparison between ABER MR and the conventional MR arthrography considering the diagnostic rate and discriminatory precision of various anteroinferior labro-ligamentous lesions. Methods: We studied 38 patients who suffered from shoulder conditions and evaluated the results of both conventional MR and ABER MR arthrography. An antero-inferior labro-ligamentous lesion was diagnosed with the detection of absence, fray, detachment, displacement of the antero-inferior labrum or detection of the contrast material inside the labrum, or avulsion, rupture of the inferior glenohumeral ligament at the humeral or labral attachment. All study subjects have undergone shoulder arthroscopy after MR technique. Results: ABER MR arthrography was associated with significant increased accuracy and diagnostic sensitivity than that of conventional MR regarding the diagnostic rate of various types of the antero-inferior labro-ligamentous lesions (p < 0.05). Conclusion: Based on our results, ABER MR arthrography would add more value to the diagnosis if the conventional MR were doubtful in suspected antero-inferior labro-ligamentous complex injuries.
