To correlate morphologic and magnetic resonance (MR) imaging findings in hamstring injury with short-term prognosis and convalescence interval (CI).
A retrospective study of 14 professional athletes with hamstring injury was performed. The injuries were categorized according to muscle group involved, percentage of cross-sectional area affected, location, and signal intensity on T1- and T2-weighted spin-echo images.
Longer CIs (> 6 weeks) were seen in injuries with complete transection, greater than 50% cross-sectional muscle involvement, ganglionlike fluid collections (long T1 and T2), hemorrhagelike signal intensity (short T1 and T2), distal myotendinous junction tears, and deep muscular tears. Shorter CIs (< 5 weeks) were seen in superficial muscle injuries and muscle belly injuries that involved small cross-sectional areas of the muscle.
Prediction of CI for high-performance athletes with complete hamstring injury may be accomplished with use of MR imaging and poor prognostic factors.
将腘绳肌损伤的形态学和磁共振（MR）成像结果与短期预后和恢复期（CI）相关联。
对14名患有腘绳肌损伤的职业运动员进行回顾性研究。根据受累肌肉群、受影响的横截面积百分比、位置以及T1加权和T2加权自旋回波图像上的信号强度对损伤进行分类。
在完全横断、横截面积肌肉受累大于50%、神经节样液体积聚（长T1和T2）、出血样信号强度（短T1和T2）、远端肌腱结合处撕裂和深部肌肉撕裂的损伤中，观察到较长的CI（>6周）。在涉及肌肉小横截面积的浅表肌肉损伤和肌腹损伤中，观察到较短的CI（<5周）。
利用MR成像和不良预后因素可以对患有完全性腘绳肌损伤的高性能运动员的CI进行预测。
