目的　采用低场MRI非增强扫描探讨强直性脊柱炎（AS）累及脊柱的MRI表现。方法　从2010年3月－2013年3月间就诊的76例AS患者的MRI图像中选取19例脊柱受累者资料，对病变部位MRI图像进行分析，评价AS累及脊柱在低场MRI非增强扫描状态下的MRI表现特点。结果　19例患者中颈椎病变3例，胸椎病变9例，腰椎病变7例；MRI表现为椎体终板炎17例、椎间盘炎13例、脊柱滑膜关节炎15例、椎旁韧带炎11例、韧带骨化和骨性强直9例。结论　低场MRI非增强扫描能直观显示AS脊柱病变，主要表现为椎体终板炎、椎间盘炎、脊柱滑膜关节炎、椎旁韧带炎、韧带骨化和骨性强直，压脂T2WI序列对活动性炎性病变显示良好，T1WI、T2WI序列能较好显示结构性病变。
