【摘要】 目的:评价螺旋CT对强直性脊柱炎(AS)骶髂关节病变的诊断价值。方法:对62例临床诊断为强直性脊柱炎的骶髂关节的CT征象参照纽约诊断标准进行分级。结果:本组中无0级表现病例;Ⅰ级:8例(占12.9%);Ⅱ级:24例(占38.7%);Ⅲ级:22例(占35.5%);Ⅳ级:8例(占12.9%)。CT表现为病变多累及骶髂关节的髂骨侧,关节面毛糙或不光整,关节面下小囊状改变;关节间隙变窄或关节融合。结论:多层螺旋CT能够准确的反映AS不同阶段骶髂关节的表现,可对AS做出早期诊断并进行CT分级,为临床分期提供客观依据。更多还原

【Abstract】 Objective:To investigate the apprearance of sacroiliac joint in patients with Ankylosing spodylitis on MSCT.Methods:MSCT manifestations of sacroiliac joints in 62 patients with ankylosing spodylitis were classified according to NewYork diagnostic criteria.Results:CT fingdings were as follows: level 0(n=0),levelⅠ(n=8,12.9%),levelⅡ(n=24,38.7%),levelⅢ,(n=22,35.5%),level Ⅳ 8(n=8,12.9%).MSCT fingdings of sacroiliac joint in patients with ankylosing spodylitis included: ilial side of sacroiliac joint was often involved;articular surface of sacroiliac joint was coarse;sacculiform lay under articular surface;narrowing joint space and joint fusion.Conclusion:MSCT is extremely accurate in early diagnosis and clinical stage of ankylosing spodylitis.更多还原
