To evaluate the diagnostic accuracy of fat-suppressed magnetic resonance (MR) imaging of rotator cuff tears in a large symptomatic population.
One hundred patients underwent both MR imaging and arthroscopy of the shoulder. Ninety-two patients underwent fat-suppressed conventional spin-echo MR imaging (repetition time msec/echo time msec = 2,500/20, 60), and eight patients underwent fat-suppressed, fast spin-echo MR imaging (2,000/80).
With data combined for complete and partial tears of the rotator cuff (n = 31), MR imaging had an accuracy of 93%; sensitivity, 84%; and specificity, 97%. Seventeen of 20 complete tears and nine of 11 partial tears were properly identified with MR imaging. Two partial tears were not detected and three complete tears were incorrectly called partial tears at MR imaging. Of two false-positive MR imaging findings, one was called a complete tear and the other, a partial tear.
Fat-suppressed MR imaging has high diagnostic accuracy in evaluating tears of the rotator cuff tendon.
评估脂肪抑制磁共振成像（MR）对大量有症状人群肩袖撕裂的诊断准确性。
100例患者均接受了肩部的MR成像和关节镜检查。92例患者接受了脂肪抑制常规自旋回波MR成像（重复时间毫秒/回波时间毫秒 = 2500/20、60），8例患者接受了脂肪抑制快速自旋回波MR成像（2000/80）。
综合肩袖完全撕裂和部分撕裂的数据（n = 31），MR成像的准确率为93%；敏感度为84%；特异度为97%。20例完全撕裂中的17例以及11例部分撕裂中的9例通过MR成像得到正确诊断。2例部分撕裂未被检测到，3例完全撕裂在MR成像时被错误地诊断为部分撕裂。在2例假阳性MR成像结果中，1例被诊断为完全撕裂，另1例被诊断为部分撕裂。
脂肪抑制MR成像在评估肩袖肌腱撕裂方面具有较高的诊断准确性。
