摘　　要：股骨头坏死是股骨颈骨折最受关注的严重并发症之一,早期预测可能出现的股骨头坏死而提早干预、避免进一步发展出现严重临床症状非常重要。目前动态对比增强MR检查是用于早期监测创伤后股骨头血供情况及再灌注状态、评价创伤后股骨头骨质活性较为敏感的非侵袭性检查技术,可为临床治疗提供有价值的影像学信息;而常规MR成像是股骨颈内固定术后早期监测股骨头坏死的可靠检查技术。Osteonecrosis of the femoral head is one of the most serious complications of neck fracture. It is very impor- tant to predict possible osteonecrosis and to intervene in time to avoid the further development of the serious clinical symp- toms. Dynamic contrast-enhanced MRI were introduced in the recent past as a non-invasive, sensitive technique to predict the vascularity and reperfusions of the femoral head and to evaluate viability of the femoral head after the femoral neck frac- tures, and may be used as a guideline for management for the fractures according these valuable imformation. Conventional MRI is a reliable tool for early diagnosis of ischemia in the femoral head after femoral neck fracture with fixation.
