Magnetic resonance imaging of shoulders with idiopathic adhesive capsulitis: reliability of measures.
The magnetic resonance imaging (MRI) findings in idiopathic adhesive capsulitis (AC) were compared with those of contralateral healthy shoulders and the reliability of measures assessed. Twenty-six consecutive patients (26 AC and 14 healthy shoulders) were prospectively assessed. The main measurements were thickness of the joint capsule and synovial membrane in the axillary recess and rotator interval in T1-weighted spin-echo sequence enhanced with intravenous (IV) gadolinium chelate (Gd-chelate). Reliability was studied by use of the intraclass correlation coefficient (ICC). The mean thickness of the axillary recess on the coronal plane was 9.0+/-2.2 mm in AC shoulders and 0.4+/-0.7 mm in healthy shoulders. The mean thickness of the rotator interval on the sagittal plane was 8.4+/-2.8 in AC shoulders and 0.6+/-0.8 mm in healthy shoulders. Interobserver reliability was good for the axillary recess, with ICC values of 0.84 for the coronal plane, and good for the rotator interval, with ICC values of 0.80 for the sagittal plane. MRI with IV Gd-chelate injection can show, with acceptable reliability, signal and thickness abnormalities of the shoulder joint capsule and synovial membrane in AC.
