目得：为了确定磁共振（MR）图像上局灶性骨坏死周围的骨髓水肿是否与临床症状相关，材料和方法：33例患者（37髋）显示早期股骨头坏死，每隔3个月随访一次，进行临床评估、常规X线检查和系列MR成像。在初始MR图像上，14个有症状的髋关节中有7个（50%）显示局灶性骨坏死周围骨髓水肿，而23个无症状髋关节中只有1个（4%）显示水肿（P
PURPOSE: To determine whether the marrow edema around focal osteonecrosis on magnetic resonance(MR) images is associated with clinical symptoms.MATERIALS AND METHODS: Thirty-three patients with 37 hips showing early stage osteonecrosis of the femoral head were followed up at 3-month intervals with clinical evaluation, conventional radiography, and serial MR imaging.RESULTS: Seven (50%) of 14 symptomatic hips showed marrow edema around focal osteonecrosis on initial MR images, whereas only one (4%) of 23 asymptomatic hips showed edema (P
