摘  要:目的:是描述慢性肺微吸入的高分辨率CT的肺纤维化表现,并通过CT的肺纤维化表现筛查GERD。方法:连续抽取食道胃镜检查证实的GERD病例的肺CT检查资料86例。通过三位具有经验的影像科医师分别读片及共同读片,最后筛选出24例资料。肺CT扫描范围从肺尖到肺底,然后0.625~1.25mm薄层骨算法重建。对所有病人CT图像进行观察,以IPIF CT表现为诊断标准提取影像表现。结果:24例CT的肺纤维化表现是:(1)班片状磨玻璃影例24(100%),其中局部中心分布22例(92%),合并周边性分布17例(70%)。(2)胸膜下蜂窝影9例(37%),其中合并间隔线影7例(3)小叶中心结节影7例(29%),其中合并小灶样实变5例。(4)牵拉性细支气管扩张15例(62%)。(5)中下段食道扩张17例(70%)。结论:GERD伴有的肺纤维化CT表现主要表现为:局部中心分布的班片状磨玻璃样影以及周边分布班片状磨玻璃影、胸膜下蜂窝影、小叶中心结节影伴食道扩张、细支气管扩张,如具有这些CT表现高度提示GERD的可能。Objective:The aim of the study was to describe the high-resolution computed tomography( CT) manifestations of chron-ic pulmonary microaspiration on the diagnosis of GERD.Materials and Methods: We reviewed the CT findings in 86 consecutive pa-tients with GERD of chronic pulmonary microaspiration proved by an endoscopy.All patients had volumetric CT of the chest reconstruc-ted using thin sections(0.625to1.25mm) at the time of diagnosis.The CT scans were interpreted by 3 radiologists who reached a final decision.We evaluated 24 patients who met criteria for the diagnosis of IPIF.Results:(1)All 24 patients (100%)had patchy ground-glass opacities that involved centrilobular in 22 patients (92%)and with peripheral 17 patients(70%).Other common findings in-cluded (2) honeycomb(n=9),(37%) (3) centrilobular nodules(n=7)(29%),(4) bronchiectasis(n=15)(62%),(5) esopha- 〈br〉 geal dilatation(n=17)(70%).Conclusions:HRCT manifestations of GERD with chronic pulmonary microaspiration consist mainly of centrilobular patchy ground-glass opacities.Centrilobular nodules, honeycomb, bronchiectasis, esophageal dilatation are seen in the majority of cases.
