目的探讨强直性脊柱炎(AS)骶髂关节病变的早期MRI表现与临床分级之间的联系.方法搜集临床确诊为AS的患者37例,均行骨盆X线和骶髂关节CT、MRI扫描,其中9例同时行MRI增强扫描.先分析X线平片、CT和MRI表现,再根据临床分级对患者进行分组,观察主要MRI征象对应的临床分期.结果 MRI扫描能清晰显示骨髓水肿、软骨损伤、脂肪沉积等表现;软骨成像序列能清晰显示骶髂关节软骨的损伤程度.增强扫描可显示早期反应.结论 X线、CT扫描不能显示病变骶髂关节的早期表现及判断炎症程度.MRI能敏感和准确地显示早期AS患者骶髂关节的滑膜增厚、骨髓水肿、关节软骨损伤等变化,并可以反映AS疾病所处的不同临床分期.

Objective Discussion early MRI findings of AS sacroiliac joint. And explore the links between MRI findings and the clinical classification. Methods Collecting 37 cases of AS patients. Underwent pelvic X ray and CT, MRI scans about sacroiliac joint. 9 cases simultaneously enhanced MRI scan. First analysis X-ray, CT and MRI features. Then according to the clinical classification for patients grouping, Observe the corresponding to the main MRI findings and the clinical staging.Results MRI scans can clearly show bone marrow edema, cartilage damage, joint effusion, fat deposition and other performance. Cartilage imaging sequences can clearly show the extent of damage to the articular cartilage of the sacroiliac joint. Enhanced scan can early response the synovitis response of sacroiliac joint.Conclusion X-ray, CT scan can not show an early manifestation of disease sacroiliac joint and determine the sacroiliac inflammation. MRI can accurately and sensitively show the synovial thickening, bone marrow edema, joint surface cartilage damage, joint effusion, cysts, fat deposition and other changes about the sacroiliac joints of early AS patients, and reflect the different clinical stages of AS.
