MRI是肩袖评价的标准治疗，临床解释通常仅限于定性判断。仅在术前或肩袖修复（RCR）后≥6个月（修复处于愈合后期）评价了基于MRI的测量和评分系统的可靠性。本研究描述了术前和术后第一年内四次评估的各种肩袖肌腱和肌肉参数的MRI评估和评估者间一致性。两名肌肉骨骼放射科医生独立评估了42名患者术前和RCR后3、12、26和52周的MRI扫描。使用标准化的阅读规则，阅片者评估肌腱完整性（5分Sugaya）、撕裂尺寸、肌肉脂肪（5分Goutallier）和萎缩（4分Warner）、肌肉横截面积和肌腱连接（MTJ）距离。使用原始精确一致率、kappa统计量和相关系数量化评定者间一致性。阅片者在RC肌腱完整性和冈上肌萎缩评分方面表现出中度至显著的概率以上一致性，在撕裂尺寸和肌肉横截面积方面表现出良好至极好的一致性，但在脂肪浸润和MTJ距离方面仅表现出一般至中度的一致性。只有脂肪浸润等级证明了观察者偏倚。评定者间一致性似乎不具有时间依赖性。在研究环境中使用定义的阅读规则，术后第一年所有时间点的RC肌腱完整性、撕裂尺寸、肌肉萎缩和横截面积的MRI评价具有合理的可靠性。然而，即使在这种有利的情况下，临床上存在显著的分歧，表明需要改进的成像工具进行精确的肩袖评估。IV级;诊断性研究
MRI is standard-of-care for rotator cuff evaluation, with clinical interpretation usually limited to qualitative judgments. The reliability of MRI–based measurements and scoring systems have been evaluated only preoperatively or ≥6 months following rotator cuff repair (RCR) when repairs are in the later stages of healing. This study describes the MRI assessments and inter-rater agreement of various rotator cuff tendon and muscle parameters evaluated preoperatively and four times during the first postoperative year. Two musculoskeletal radiologists independently assessed MRI scans of 42 patients preoperatively and 3, 12, 26 and 52 weeks after RCR. Using standardized reading rules, readers assessed tendon integrity (5-point Sugaya), tear dimensions, muscle fat (5-point Goutallier) and atrophy (4-point Warner), muscle cross-sectional areas and myotendinous junction (MTJ) distance. Raw exact agreement proportions, kappa statistics, and correlation coefficients were used to quantify inter-rater agreement. Readers showed moderate to substantial above-chance agreement in scoring RC tendon integrity and supraspinatus muscle atrophy, good to excellent agreement on tear dimensions and muscle cross-sectional areas, but only fair to moderate agreement for fatty infiltration and MTJ distance. Only fatty infiltration grades evidenced observer bias. Inter-rater agreement did not appear time dependent. Using defined reading rules in a research setting, MRI evaluations of RC tendon integrity, tear dimensions, muscle atrophy and cross-sectional areas have reasonable reliability at all time points in the first postoperative year. However, the presence of clinically significant disagreements, even in such favorable circumstances, indicates need for improved imaging tools for precise rotator cuff evaluation.
