| 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 reconstruction,
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 performance
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 of ankylosing spondylitis in the sacroiliac joint disease in the differential diagnosis and classification has great
value, should be preferred in patients with clinically suspicious checks. |
