摘　　要：目的分析研究CT和磁共振成像(MRI)在髋臼缺血性坏死病因中的临床应用价值,以提高对髋臼缺血坏死的认识。方法回顾性分析本院2014年8月至2017年1月诊治的38例多种病因伴发的髋臼缺血性坏死的CT和MRI的影像资料。10例行CT检查,26例行MRI检查,2例行CT及MRI检查。结果 38例患者中,晚期(Ⅲ~Ⅳ期)股骨头缺血性坏死19例,成人髋臼发育不良8例,髋关节退行性骨关节病5例,强直性脊柱炎(AS)3例,系统性红斑狼疮2例,髋臼粉碎性骨折术后感染1例。髋臼软骨变性、坏死及髋臼的骨髓水肿为MRI特征性表现,髋臼骨质的囊变坏死的显示MRI优于CT,髋臼骨小梁中断、碎裂、皮质塌陷及骨质疏松改变CT优于MRI。结论 CT和MRI在髋臼缺血性坏死病因分析及诊断有十分重要的价值。Objective To analyze and study the clinical value of CT and MRI in the etiology of acetabular ischemic necrosis, so as to improve the understanding of acetabutar ischemic necrosis. Methods The imaging data of CT and MRI in 38 cases of ischemic necrosis of the acetabulum accompanied by various etiologies in our hospital from August 2014 to January 2017 were analyzed retrospectively. 10 cases were examined by CT, 26 cases underwent MRI examination, 2 cases underwent CT and MRI examination. Results Among the 38 patients, there were 19 cases of avascular necrosis of the femoral head in the late stage （stage Ⅲ-Ⅳ）, 8 cases of adult acetabular dysplasia, 5 cases of degenerative osteoarthritis of the hip, 3 cases of ankylosing spondylitis （AS） ,2 cases of systemic lupus erythematosus,acetabular comminuted fracture postoperative infection in 1 cases. Acetabular cartilage degeneration, necrosis and acetabular bone marrow edema for the MRI characteristics of the performance of acetabular bone cystic necrosis showed better than CT, acetabular trabecular interruption, fragmentation, cortical collapse and osteoporosis CT is better than MRI. Conclusion CT and MRI are of great value in the analysis and diagnosis of ischemic necrosis of the acetabulum.
