| 摘 要： | 目的 探讨强直性脊柱炎(AS)骶髂关节(SIJ)病变的低场MRI的诊断价值.方法 回顾性分析临床确诊的37例ASSIJ病变患者的MRI表现,并与X线、CT表现进行比较.结果 37例AS患者中,34例MRI显示SIJ软骨异常、19例显示关节下骨髓水肿、21例显示脂肪沉积、29例显示骨质破坏、11例合并髋关节病变.X线平片检出SIJ病变0～Ⅰ级14例、Ⅱ级4例、Ⅲ级14例、Ⅳ级5例;CT检出SIJ病变0级4例、I级3例、Ⅱ级12例、Ⅲ级13例、IV级5例;MRI检出SIJ病变Ⅰ级7例、Ⅱ级14例、Ⅲ级11例、Ⅳ级5例.结论 低场MRI可清晰地显示SIJ软骨异常、骨髓水肿、脂肪沉积及早期骨侵蚀改变,是ASSIJ病变早期首选影像学诊断方法.

| Abstract: | Objective To explore the diagnostic values of low field MRI for sacroiliac joints lesions in ankylosing spondylitis. Methods MRI features of 37 cases with sacroiliac joints lesions from ankylosing spondylitis were retrospectively analyzed and compared with X-ray and CT manifestations. Results As for the MR images of the 37 ankylosing spondy-litis cases,cartilage changes of sacroiliac joints was found in 34 cases,subchondral bone marrow edema was noted in 19 cases,fatty deposition was found in 21 cases,bone ... |
