To determine if fast spin-echo (SE) magnetic resonance (MR) imaging can provide similar information to that of conventional SE imaging for evaluation of the rotator cuff.
One hundred twenty-six patients underwent MR imaging with conventional SE and non-fat-suppressed fast SE sequences (65 patients) or conventional SE and fat-suppressed fast SE sequences (61 patients). Two radiologists independently graded the rotator cuff with separate and side-by-side assessment of the fast SE and conventional SE images.
For detection of full-thickness tears, agreement between non-fat-suppressed fast SE and conventional SE images was 93.8% (kappa = 0.78 [good]) and 95.4% (kappa = 0.82 [very good]) for the two readers, respectively, and agreement between fat-suppressed fast SE and conventional SE images was 98.4% (kappa = 0.96 [very good]) and 91.8% (kappa = 0.73 [good]) for the two readers, respectively. Rotator cuff grading was similar for fast SE and conventional SE: weighted kappa = 0.77 (good) and 0.68 (good) for non-fat-suppressed and weighted kappa = 0.83 (very good) and 0.67 (good) for fat-suppressed fast SE images for the two readers, respectively.
Fast SE sequences yield similar interpretations as those obtained with a conventional SE sequence for evaluation of the rotator cuff.
确定快速自旋回波（SE）磁共振（MR）成像在评估肩袖时能否提供与传统SE成像相似的信息。
126例患者接受了传统SE序列及非脂肪抑制快速SE序列（65例患者）或传统SE序列及脂肪抑制快速SE序列（61例患者）的MR成像。两名放射科医生分别独立地对快速SE图像和传统SE图像进行并排评估，对肩袖进行分级。
对于全层撕裂的检测，两名读者中，非脂肪抑制快速SE图像与传统SE图像之间的一致性分别为93.8%（kappa = 0.78[良好]）和95.4%（kappa = 0.82[非常好]），脂肪抑制快速SE图像与传统SE图像之间的一致性分别为98.4%（kappa = 0.96[非常好]）和91.8%（kappa = 0.73[良好]）。快速SE和传统SE对肩袖的分级相似：两名读者中，非脂肪抑制快速SE图像的加权kappa分别为0.77（良好）和0.68（良好），脂肪抑制快速SE图像的加权kappa分别为0.83（非常好）和0.67（良好）。
在评估肩袖时，快速SE序列与传统SE序列的解读结果相似。
