早期强直性脊柱炎的X线、CT、MRI诊断价值(1)
【中图分类号】R681.5【文献标识码】A【文章编号】1672-5085(2008)02-0147-02【摘要】目的：探讨强直性脊柱炎X线、CT、MRI表现及其诊断价值。方法：对70例诊断为强直性脊柱炎的影像学资料进行了回顾性分析和总结。结果：70例均行X平片均发现Ⅲ级以上的骶髂关节改变，主要表现为关节面破坏、间隙狭窄和关节强直，其中45例行CT检查发现Ⅲ级以下骶髂关节的改变，27例MRI检查显示关节腔、关节软骨、骨髓信号及关节囊等改变。结论：强直性脊柱炎具有特征性的影像学表现，三种检查方法各有优势，影像学检查仍以x线平片为首选方法，若诊断有困难或需要与其他疾病鉴别时则考虑有选择性地应用CT、MRI检查。
