To review experience with the imaging features of hamstring injuries.
Imaging findings in 18 male and four female patients with clinically proved hamstring injuries were reviewed. The patients' ages ranged from 13 to 61 years (mean, 26 years). Radiography, conventional tomography, computed tomography (CT), and magnetic resonance (MR) imaging were performed.
Plain radiographs obtained less than 1 week after injury were normal or showed avulsion of an ischial apophysis. Plain radiographs and conventional tomograms obtained more than 1 week but less than 3 months after injury were confusing, because callus and osteolysis were present. CT helped identify a healing avulsion of an ischial apophysis. MR imaging was helpful no matter how long after the injury it was performed. It provided a means to evaluate muscle, tendon, and bone.
Familiarity with the variable appearance of hamstring injuries over time and with different modalities facilitates accurate characterization.
回顾腘绳肌损伤的影像学特征。
回顾18例男性和4例女性经临床证实的腘绳肌损伤患者的影像学表现。患者年龄为13至61岁（平均26岁）。进行了X线摄影、传统体层摄影、计算机断层扫描（CT）和磁共振成像（MR）检查。
受伤后1周内的X线平片正常或显示坐骨骨突撕脱。受伤后1周以上但不到3个月的X线平片和传统体层摄影结果令人困惑，因为有骨痂和骨质溶解。CT有助于识别坐骨骨突愈合性撕脱。无论受伤后多久进行MR成像都很有帮助。它提供了一种评估肌肉、肌腱和骨骼的方法。
熟悉腘绳肌损伤随时间推移和不同检查方式的不同表现有助于准确诊断。
