摘　　要：目的:评价多层CT诊断强直性脊柱炎骶髂关节病变的价值。方法:对32例患者行骶髂关节16层螺旋CT扫描,患者取仰卧位,采用各向同性的扫描,原始采集层厚0.75mm,矩阵512×512,层厚3mm,在工作站进行三维骨成像处理,包括多平面重建、最大强度投影和容积再现。结果:23例表现为不同程度关节面模糊、破坏,表现为软骨下骨质虫蚀状改变,11例发现皮质下小囊状透亮区。按CT表现分级,11例属于I级,8例属于Ⅱ级,8例属于Ⅲ级,5例属于IV级。结论:多层CT在强直性脊柱炎骶髂关节病变的鉴别诊断与分级中有较大价值,应作为临床可疑患者的优选检查。Objective： To evaluate the multi-slice CT diagnosis of ankylosing spondylitis sacroiliac joint lesions. Methods： 32 patients underwent 16-slice spiral CT scan in sacroiliac joint, the patient supine, using isotropic scanning, the original acquisition slice thickness 0.75mm, matrix 512×512, slice thickness 3mm. In workstation the three-dimensional bone imaging including multi-planar re- construction, maximum intensity projection and volume rendering. Results： 23 cases showed varying degrees of articular surface blur, damage, expressed as worm-eaten-like subchondral bone changes found in 11 patients with subcortical small cystic lucent zone. The per- formance of classification by CT, 11 cases belong to class Ⅰ, 8 cases belonging to grade Ⅱ, 8 cases are Ⅲ, 5 patients belong to class IV. Conclusion： Multislice CT ofankylosing spondylitis in the sacroiliac joint disease in the differential diagnosis and classification has great value, should be preferred in patients with clinically suspicious checks.
