摘要目的 研究暂时性骨质疏松的MRI表现.方法 回顾性分析6例暂时性骨质疏松的MRI表现.6例均行常规轴位MR T1WI和12WI及冠状位T1WI、T2WI、STIR像.6例中男4例女2例,年龄为15～65岁.结果 6例均为双髋部病变.T1WI呈低信号,T2WI正常信号1例,中-高信号2例,高信号3例.STIR像均为不同程度的高信号.见髋臼受累1例,股骨头受累2例,关节腔积液6例.结论 MRI是诊断暂时性骨质疏松的最佳方法.

abstractsObjective To study MRI features of transient osteoporosis.Methods MR imaging of transient osteoparosis in six patients was retrospectively reviewed.In all six patients.routine scanning was performed in axial and coronal planes,including T1-weighted imaging,and coronal STIR imagine.Of the six patients,four were male,two were female,with the age ranging from 15～65 years.Results The bilateral hips were affected in six patients.The MR images demonstrated low signal intensity in all six patients on T1 WI and normal signal intensity(1 cage),medium-high sioua intensity(2 cases),high signal intensity(3cases),and STIR imaging showed high signal intensity(6 cases).Bone diseases involved the acetabulum(one hip),the femoral hesd(two hips)and a small joint effusion Wma observed in six cases.Conclusion MRI is the best method for diagnosing the transient osteoporosis.
