目的:探讨MRI对强直性脊柱炎髋关节病变的早期诊断价值。方法:对临床证实的20例强直性脊柱炎患者髋关节病变的MRI表现进行回顾性分析。结果:20例均有不同程度髋关节积液。18例关节间隙增宽,2例关节间隙稍变窄。增强扫描20例髋关节腔内出现不同程度的强化,并且3例同时伴有髋臼、股骨头内异常对比增强。结论:强直性脊柱炎髋关节病变的早期MRI主要表现为髋关节积液、滑膜增厚强化。
Objective: To investigate the value of MRI in the early diagnosis of hip joint disease in ankylosing spondylitis. Methods: The clinical manifestations of hip arthropathy in 20 patients with ankylosing spondylitis were retrospectively analyzed. Results: All 20 patients had different degrees of hip joint effusion. 18 cases of joint space widened, 2 cases of joint space narrowed slightly. Enhanced scanning of 20 cases of hip cavity showed varying degrees of enhancement, and 3 cases accompanied by acetabulum, femoral head abnormalities increased contrast. Conclusion: Early MRI of ankylosing spondylitis in hip joint mainly presents as hip joint effusion and synovial thickening.
