目的：探讨强直性脊柱炎（AS）骶髂关节（SIJ）改变的MRI早期诊断价值。方法回顾2012年6月～2013年9月临床明确诊治的15例AS患者SIJ的MRI表现，重点分析其骨软骨、关节间隙、骨髓、韧带附着处等的影像学征象，采用DR/CT分级标准进行对照研究。结果 MRI对SIJ“三线解剖”显示有优势，对软骨的早期侵蚀和骨髓炎性水肿的变化极敏感，早期诊断较CT敏感一至二个级别，并易于早期发现毗邻关节、骨质、附着处病变。结论MRI对AS的SIJ影像表现具有较高的临床早期诊断价值。

Objective To investigate the early diagnostic value of MRI in sacroiliac joint(SIJ) change of ankylosing spondylitis(AS). Methods The MRI manifestation of SIJ in 15 patients of AS with clinical definite diagnosis and treatment during June 2012 to September 2013 were reviewed,and the analysis was focused on the imaging findings of osteochondral,joint space,bone marrow and ligament attachment,and the control study was done by using the DR/CT classification criteria. Results MRI had the advantage on“three line display anatomy”of SIJ,and was very sensitive to the changes in early erosion of cartilage and marrow oedema,and the early diagnosis sensitivity of MRI increased by one to two levels compared with CT,and is easy to found the early lesion of adjacent joint,sclerotin and attachment. Conclusion MRI has higher early clinical diagnosis value on the imaging performance of SIJ in AS.
