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.
将特发性粘连性关节囊炎（AC）的磁共振成像（MRI）结果与对侧健康肩部的结果进行比较，并评估测量的可靠性。对26例连续患者（26个AC肩部和14个健康肩部）进行前瞻性评估。主要测量指标为在静脉注射钆螯合物（Gd-螯合物）增强的T1加权自旋回波序列中，腋窝隐窝处关节囊和滑膜的厚度以及旋转间隙。通过组内相关系数（ICC）研究可靠性。AC肩部冠状面上腋窝隐窝的平均厚度为9.0±2.2毫米，健康肩部为0.4±0.7毫米。AC肩部矢状面上旋转间隙的平均厚度为8.4±2.8毫米，健康肩部为0.6±0.8毫米。观察者间对腋窝隐窝的可靠性良好，冠状面的ICC值为0.84，对旋转间隙的可靠性也良好，矢状面的ICC值为0.80。静脉注射Gd-螯合物的MRI能够以可接受的可靠性显示AC中肩关节囊和滑膜的信号及厚度异常。
