摘要 目的探讨强直性脊柱炎(AS)髋关节改变的X线、CT和MRI影像表现,比较三者显示AS髋关节受累效果。方法对40例AS髋关节改变患者分别行X线平片、单排螺旋CT和MRI检查,观察三组影像效果,并作出临床操作难度、图像质量、诊断准确率及受累敏感度等指标评价。结果在患者舒适度、图像清晰度和诊断准确率方面螺旋CT和MRI检查要显著高于X线平片,但在操作难度上前二者却明显低于后者(P<0.05);在图像质量、操作难度和患者舒适度方面,螺旋CT与MRI对比差异无统计学意义(P>0.05);MR诊断准确率要高于螺旋CT检查(P<0.05)。结论 X线、CT和MRI检查均能对AS髋关节改变作出诊断,但相比X线、CT,MRI更能清晰地显示髋关节受累时的急性炎性反应,可作为临床影像学手段诊断早期AS髋关节改变的首选方法。
