Fatigue fracture represents a spectrum of osseous stress injuries, and occurs when bone responses to abnormal repetitive stress. It is particularly common in the athletics-related populations. The vast majority affect the lower extremity. Due to lack of specificity, fatigue fractures may mimic other musculoskeletal diseases. Early and accurate diagnosis is important in planning treatment and improving prognosis of fatigue fracture. This paper mainly introduced the progresses of various radiological methods (X ray, CT, scintigraphy, MRI, and ultrasound) which are available for detecting fatigue fracture.%疲劳性骨折是骨骼应力损伤性疾病，为反复异常应力作用于正常骨骼所致，与运动有关的人群好发，主要集中于下肢，临床表现缺乏特异性，易误诊为其他骨骼肌肉病变，早期准确诊断疲劳性骨折对指导临床治疗和改善预后有重要意义。主要介绍诊断疲劳性骨折的X线、CT、核素、MRI及超声等医学成像检查方法的相关研究进展。
