Abstract Purpose:By analyzing the characters of CT images of pneumoconiosis, discussing the value of diagnosis. Material and method: 85 different stage patients of pneumoconiosis that being made a definite diagnosis have a CT scan of chest, and their are pare with X ray images. Result: CT image can demonstrate the lung’s changes of pneumoconiosis, for example, shape, size, distribution and following appearances of the shadow, especially, CT images have the value of antidiastole of the shadow of pneumoconiosis Ⅲ.

尘肺病是由于在职业活动中长期吸入生产性粉尘并在肺内潴留而引起的以肺组织弥漫性纤维化为主的全身性疾病,是一种严重危害人民健康的职业性疾病。近几年,随着工矿企业的迅猛发展,由于职业卫生防护意识不足,尘肺病发病有增高趋势。尘肺病的诊断,国家有严格的标准,但都是以普通高千伏X线片作为诊断片,并对照国家尘肺标准片,由具有职业病诊断资格的专业人员集体进行诊断,并没有相应的CT标准,导致CT诊断人员对尘肺病认识不足,造成误诊误治。现将我院1997-2007年确诊尘肺病例中具有CT资料的共85例,进行分析报告如下,以供参考:
