摘　　要：目的：探讨MRI在髋关节一过性骨质疏松症（TOH）中的诊断价值.方法：回顾性分析12例髋关节TOH患者的临床和影像学资料.髋关节MRI以轴位及冠状位T1WI、T2WI及抑脂序列扫描为主.结果：12例TOH均无骨软骨骨折,均为单侧髋关节发病.均在患侧髋关节骨质内出现骨髓水肿区,其中6例病变局限于股骨头、3例位于股骨头及颈部,3例病变位于股骨头、颈部及股骨粗隆间骨质.MRI随访3-13月,病灶基本消失.结论：MRI随访可反映出TOH病理变化过程,是TOH诊断准确可靠的影像学检查方法.AIM： To investigate the diagnostic value of MRI in transient osteoporosis of the hip. METHODS： The clinical material and imaging data of 12 patients with TOH were retrospectively analyzed. Of the twelve patients,9 were male and 3 were female,with the age ranging from 15 to 48（ mean 38. 5） years. One female patient developed the condition during pregnancy. MRI scanning was performed in axial and coronal planes with Tl-weighted,T2-weighted and fat suppression. RESULTS： All 12 cases of TOH had no osteochondral fractures,and patients were all involved in the unilateral hip. On MRI imagings,bone marrow edema could be seen in all involved hip. The lesions were restricted within the femoral head in 6 cases,extended to the femoral neck in 3 cases,and to the head,neck and intertrochanteric region in3 cases. With follow-up MRI from 3 to 13 months,the lesions almost disappeared. CONCLUSION： MRI follow up can reflect the process of pathological changes in TOH,and it is an accurate and reliable method of TOH diagnosis.
