摘要
目的 :拟定强直性脊柱炎 (AS)的早期 (Ⅰ期 )影像学诊断标准。方法 :14 63例骶髂关节CT检查中 ,正常 2 84例 ,AS 1179例 ,Ⅰ期 483例 ,并经过中西医结合治疗 ,以及治疗前后影像学对比观察。结果 :正常骶髂关节 :①关节面光整 ,骨皮质密度均匀 ,厚薄一致 ;②关节间隙宽度呈左右、上下对称一致 ;③紧靠关节面骨皮质的松质骨小梁清晰可辨。Ⅰ期AS的影像学表现为 :①髂骨侧关节面骨皮质模糊 ,浓密不均 ,部分骨皮质消失或完全消失 ;②髂骨侧紧靠骨皮质的松质骨小梁难以辨认 ;③关节间隙狭窄。Ⅰ期AS经过中西医结合治疗后可完全痊愈 ,未经治疗的Ⅰ期变为Ⅱ期 ,即关节面出现缺损。结论
Objective:To make out the diagnostic criterion of early imaging diagnosis (stageⅠ) of the ankylosing spondylitis (AS). Methods:Among the 1463 CT scans of the sacroiliac joint(SIJ),284 cases showed normal findings, and 483 cases with stageⅠ AS were depicted from the rest of 1179 scans with AS. The patients with stageⅠ AS received the combined treatment of traditional Chinese medicine and western medicine , and then their imaging data before and after treatment were analysed and compared.Results:The normal SIJ had the following manifestations: ①The surface of the joint was smooth, and the cortex revealed uniform density and thickness.②The joint space was symmetrical in both sides.③The trabecula adjacent to the cortex of the joint could be identified clearly. On the other hand, the imaging findings of the stageⅠ AS could be summarized as follows:①The cortex of the joint surface at the ilium side was hazzy and with inhomogenous density, and part or all of the cortex disappeared.②The trabecula adjacent to the joint surface of the ilium was hardly identified.③Narrowing of the joint space.These patients could be cured after the combined treatment of traditional Chinese medicine and western medicine. Some patients with stage I untreated, however, could become worse and progressed into stageⅡ with defects on the joint surface.Conclusion:The imaging diagnosis of the stageⅠ AS described above has been proved to be correct by the follow up examination after the treatment.
