Diagnosis of adhesive capsulitis: comparison of contrast-enhanced MRI with noncontrast-enhanced MM

초록

Objective: To compare the diagnostic performance of contrast-enhanced (CE) magnetic resonance imaging (MRI) and non-CE MRI for adhesive capsulitis (AC). Methods: CE MRI of 50 AC and 53 non-AC patients were reviewed by two radiologists independently. Results: Axillary capsular thickening and T2 hyperintensity (sensitivity=92-94%; specificity=53-64%) and enhancement of the axillary capsule and rotator interval (sensitivity=92-98%; specificity=38-64%) were helpful in diagnosing AC. Interobserver reliability was highest with axillary joint capsule enhancement (K=0.92). Conclusion: Non-CE and CE MRI are helpful in confirming the clinical diagnosis of AC. CE-MRI may improve assessment of the rotator interval and diagnostic confidence in patients with AC (C) 2015 Elsevier Inc. All rights reserved.
