目的:研究暂时性骨质疏松的MRI表现。方法:回顾性复习6例暂时性骨质疏松的MR表现。6例均行常规轴位MRI T1WI和T2WI及冠状位T1WI、T2WI和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。
Objective: To study the MRI manifestations of transient osteoporosis. Methods: The MR findings of 6 cases of temporary osteoporosis were retrospectively reviewed. 6 cases underwent conventional axial MRI T1WI and T2WI and coronal T1WI, T2WI and STIR images. 6 males in 4 cases, 2 females, aged 15-65 years old. Results: All 6 cases were double hip lesions. T1WI showed low signal, T2WI normal signal in 1 case, medium-high signal in 2 cases, high signal in 3 cases. STIR images are high levels of signal. See acetabular involvement in 1 case, femoral head involvement in 2 cases, 6 cases of joint effusion. Conclusion: MRI is the best method to diagnose temporary osteoporosis.
