摘　　要：目的:评价CT、MRI对疲劳骨折的影像诊断价值。材料与方法:回顾分析21例经随访证实的疲劳骨折的X线平片、CT、MRI征象。结果:与传统X线比较,CT、MRI更容易发现疲劳骨折的骨折线,并且更容易显示其相对早期改变。结论:疲劳骨折通常根据临床和X线平片即可明确诊断,但CT、MRI结合X线平片对疲劳骨折的影像诊断具有较高的敏感性和特异性,有助于疲劳骨折的早期诊断及鉴别诊断。Purpose： To evaluate the value of CT and MRI in the diagnosis of fatigue fracture. Materials and Methods： Characteristic X -ray plain film, CT and MR findings in 21 patients fatigue fracture were retrospectively analyzed. Results： Compared with conventional radiographs examinations, CT and MRI could not only show fracture lines, but also reveal relatively early changes and more information of fatigue fracture. Conclusion： Fatigue fracture can be diagnosed according to clinical appearance and X - ray plain film, but X - ray plain film incorporate CT and MR/ possessed a high sensitivity and specificity, and was an important method on the diagnosis of fatigue fracture .
