摘要
目的探讨各MR成像序列显示骶髂关节炎病变的优势。资料与方法回顾分析55例典型强直性脊柱炎的骶髂关节MRI资料,扫描序列为SE-T1WI、TSE-T2WI、FFE-T2WI、SPIR,观察各序列对病变的显示情况,计算病变的显示率。结果FFE-T2WI序列显示关节软骨及骨质硬化最佳;SPIR序列对关节旁水肿最有优势;而对于骨关节面的侵蚀,SE-T1WI、TSE-T2WI、FFE-T2WI序列均可有较为满意的显示。
Objective To evaluate the advantage of different MR sequences in the lesion detection of sacroilitis,Methods SE-T1WI、 TSE-T2WI、 FFE-T2WI、 SPIR, four sequences were performed in 55 patients with sacroilitis. Different sequences in displaying the lesions were observed and compared. The displaying rate of different sequences was calculated. Result FFE-T2WI sequences is best to display the abnormity arthrosis cartilage and the bone cirrhosis, SPIR sequence is best in displaying the bone marrow edema, and for the erosion of joint surface, SE-T1WI、 TSE-T2WI、FFE-T2WI can display satisfied quietly.
