IDEAl-IQ技术联合功能评分对肩袖损伤的研究
摘要
诊断与严重程度分级中的应用价值。方法：纳入67例肩袖损伤患者，根据Sugaya分级分为A组（正常/肌腱病，15
例）、B组（部分撕裂，37例）、C组（小全层撕裂，7例）及D组（中/大全层撕裂，8例）。所有患者行肩关节MRI
检查，测量冈上肌、冈下肌、肩胛下肌及小圆肌的FF值，并收集Constant与ASES评分。比较组间差异并通过ROC
曲线分析各参数的诊断效能。结果：冈上肌FF值在四组间差异具有统计学意义（P=0.006），且随损伤加重而升高
（D组中位数5.63%）。Constant与ASES评分随损伤加重而显著下降（P=0.001）。ROC曲线显示，冈上肌FF值在鉴别
全层撕裂（C、D组）与非全层撕裂（A、B组）时效能良好（AUC=0.805），联合肩关节功能评分后诊断效能更优
（AUC=0.805，灵敏度73.3%，特异度75.0%）。结论：IDEAL-IQ定量测量的冈上肌FF值与肩关节功能评分密切相
关，二者联合能更全面、准确地评估肩袖损伤严重程度，为临床诊疗决策提供重要依据。
