摘要
目的：探讨早期强直性脊椎炎的影像学表现特征.方法：回顾性分析2008年1月至2012年12月广东药学院附属门诊部和广东省中医院收治的36例AS患者的影像学资料,观察患者X线片和CT检查的特点.结果：早期病变部位多位于双侧骶髂关节中下部并以髂骨侧为著,主要表现为双侧骶髂关节面不清,边缘模糊、毛糙,虫蚀样骨质破坏、关节面下小囊变,邻近骨质轻度硬化;CT扫描能更清楚显示骶髂关节细微改变,对早期病变（0～Ⅱ级）提高了I～Ⅱ个诊断级别.结论：CT扫描对AS病变的早期发现与分期更准确,可提高AS早期诊断率.
Objective：To investigate the imaging features of early stage ankylosing spondylitis. Methods： We did a retrospective analysis on the imaging characteristics, including X-ray plain film and CT scan, of 36 patients with ankylosing spondylitis （AS） who were admitted to Affiliated Out-patient Clinics of Guangdong College of Pharmacy between January 2008 and December 2012. Results： Early-stage AS mostly involved the lower pportion and iliac side of bilateral sacroiliac joints, which mainly demonstrated coarse surfaces and edges, eroded bone destruction, articulate cystosis and mild hardening of adjacent bones. CT scan more clearly demonstrated subtle changes of the sacroiliac joints, as evidenced by an improvement of 1 to 2 diagnostic level of the early-stage lesions （grade 0 -Ⅱ ）. Conclusion： CT scan offers increased accuracy for demonstration of early-stage lesions and staging, which is associated with improved diagnosis of AS.
