摘要
目的探讨下肢长骨疲劳性骨折的MRI诊断价值。方法回顾性分析14例经临床随访证实的疲劳性骨折MRI影像资料。结果与传统X线及CT比较,MRI不仅能显示疲劳性骨折的骨折线,而且能显示骨折周围软组织、髓腔内的水肿和出血,骨折线及骨膜增生在T1WI和T2WI均呈低信号,尤其STIR像对诊断最有价值。结论 MRI对疲劳性骨折的早期诊断和鉴别诊断具有重大意义。
Objective To investigate the MRI feature of fatigue fracture of the long bone of the lower limb.Methods The MRI data of 14 cases with fatigue fracture confirmed by clinical diagnosis were retrospectively analyzed.Results Compared with conventional radiograph and CT examination,MRI could demonstrate not only the fracture line,but also the soft tissue and the swelling and hemorrhage of marrow cavity.The fracture line and periosteal proliferation were low signal intensity on T1WI and T2WI,especially STIR images.Conclusion MRI is of great value in the early diagnosis and differential diagnosis of fatigue fracture.
