摘要目的:研究慢性阻塞性肺疾病患者胸部高分辨CT(HRCT)不同表型与肺功能之间关系,探索慢性阻塞性肺疾病胸部影像学表型的临床应用价值。方法:纳入慢性阻塞性肺疾病患者60例为研究对象,将患者胸部HRCT表型分为A型(无严重肺气肿,伴或不伴支气管壁增厚)、E型(仅严重肺气肿,无支气管壁增厚)及M型(严重肺气肿伴支气管壁增厚),比较各表型患者肺功能差异。结果:3组患者肺通气功能一秒率(FEV1/FVC)存在差异(P<0.001),A型较E型和M型(均P<0.001)好;E型与A型患者肺弥散功能存在差异(P<0.05),E型较A型差。结论:胸部HRCT肺气肿严重者肺功能较差,肺气肿较支气管壁增厚对肺功能影响更为显著。
