Abstract： 目的评价抗结核化疗前后早期和(或)活动性肺结核的高分辨率CT(HRCT)征象.方法总结了2组共100例肺结核病例的HRCT检查所见.活动性肺结核诊断依据痰抗酸杆菌染色阳性(75例)及治疗期间获得的一系列胸部影像学改变(25例).对另5例死于肺结核的尸体肺予以病理-影像对照.结果在初诊组(66例)与复发组(34例)肺结核HRCT检查中,小叶中心病变(93例,占93.0%)、树芽状(76例,占76.0%)及支气管管壁增厚(70例,占70.0%)均为检出率较高的征象,与其他征象检出率相比差异有非常显著性意义(P<0.001).结论小叶中心病变是早期和(或)活动性肺结核最常见并较有特征性的HRCT征象,若再与其他有较高特异性的HRCT征象及临床资料相结合,则有助于早期和(或)活动性肺结核的诊断和鉴别诊断.
