Three patients with transient osteoporosis of the hip underwent magnetic resonance (MR) imaging. MR images showed decreased signal intensity of bone marrow in the femur on T1-weighted images and increased signal intensity relative to the intensity of normal bone marrow on T2-weighted images. Joint effusions were seen on MR images of all patients on T2-weighted images. The findings on MR images concurred with histologic findings, such as increased bone turnover and mild inflammatory reaction, in one patient. The clinical symptoms and abnormalities on MR images regressed completely within 6-10 months. Familiarity with the distinct features of transient osteoporosis on MR images may be important in the differential diagnosis of adults with hip pain.
三名患有髋部短暂性骨质疏松症的患者接受了磁共振（MR）成像检查。MR图像显示，在T1加权图像上股骨骨髓信号强度降低，而在T2加权图像上相对于正常骨髓强度信号强度增加。在所有患者的T2加权图像上均可见关节积液。一名患者的MR图像表现与组织学结果相符，如骨转换增加和轻度炎症反应。临床症状和MR图像上的异常在6至10个月内完全消退。熟悉MR图像上短暂性骨质疏松症的独特特征对于成人髋部疼痛的鉴别诊断可能很重要。
