摘　　要：目的:探讨CT在诊断多发性肌炎和无肌病的皮肌炎肺损害的价值.材料和方法:使用东芝Asteion四层螺旋CT机对2001年6月～2003年12月我院收治的7例确诊皮肌炎患者的肺部进行扫描.结果:磨玻璃状阴影7例;小叶间隔增厚6例,胸膜下弧线影6例,支气管血管束影像异常改变7例,胸膜增厚7例,轮状或蜂窝状阴影5例,主要分布于两下肺野及胸膜下区.结论:CT可作为诊断多发性肌炎和无肌病的皮肌炎肺部损害的有效手段.To study computed tomography characteristic of pulmonary involvement attributed to polymyositis and amyopathic dermatomyositis.Materials and Methods:Seven cases of polymyositis and amyopathic dermatomyositis were examined by CT.Results:Findings of CT studies included multiple focal ground-glass opacities(n=7),interlobular septal thickening(n=6),subpleural lines(n=6),ir-regular peribronchovascular thickening(n=7),pleural thickening(n=7),honeycombing(n=5).These findings were more remarkable in the lower portion and the subpleural area of the lungs.Conclusion:CT was an effective method in evaluating pulmonary involvement attributed to polymyositis and amyo-pathic dermatomyositis.
