Abstract
目的 评价T1WI、T2WI、TIRM-T2WI及3D-MEDIC-WE序列对骶髂关节炎关节软骨病变的诊断价值.方法 收集临床高度怀疑骶髂关节炎的患者60例,另选取20例志愿者作为对照组.在3D-MEDIC-WE序列上测量对照组骶髂关节软骨厚度;在TIRM-T2WI、3D-MEDIC-WE序列上分别对患者组骶髂关节软骨进行分级评分.结果 正常骶髂关节软骨厚约(2.70 ±0.41)mm,骶侧软骨厚约(1.21 ±0.22) mm,髂侧软骨厚约(0.72±0.31)mm,骶侧软骨比髂侧软骨明显厚、约为其2倍(P＜0.01).患者组在3D-MEDIC-WE序列上的软骨侵蚀分数高于TIRM-T2 WI序列(P＜0.01).结论 3D-MEDIC-WE序列可以清晰显示骶髂关节软骨;3D-MEDIC-WE序列对骶髂关节炎关节软骨病变的显示优于其他序列.
