【摘要】：目的分析小儿感染后闭塞性细支气管炎(PIBO)的肺部双源Flash CT影像表现,结合影像征象初步探讨其与病理关系。方法回顾性分析65例符合临床PIBO诊断标准的患儿肺部双源Flash CT影像资料,观察主要征象、肺纹理变化及辐射剂量情况。结果 65例PIBO患儿肺部CT征象:马赛克征65例(100%),段和/或亚段支气管壁增厚64例(98.5%),支气管扩张20例(30.8%),细支气管壁增厚42例(64.6%),细支气管扩张11例(16.9%),伴随炎性渗出性病变54例(83.1%)。其中马赛克征中肺密度减低区内肺纹理细少38例(58.5%),无明显变化20例(30.8%),略增粗7例(10.8%)。有效辐射剂为(1.08±0.65)m Sv。结论小儿PIBO的主要CT征象是马赛克征、大气道壁和细支气管壁增厚,其高发生率、弥漫分布的表现高度提示免疫机制可能参与PIBO的发病过程;其中细支气管改变的情况对PIBO的诊断及临床治疗具有重要指导意义。
[Abstract]:Objective to analyze the CT findings of pulmonary duplex Flash in children with bronchiolitis obliterans (PIBO), and to explore the relationship between the CT findings and pathology.Methods the CT imaging data of 65 children with double source Flash were analyzed retrospectively. The main signs, changes of lung texture and radiation dose were observed.Results in 65 cases of PIBO, pulmonary CT signs were: mosaic sign in 65 cases, bronchial wall thickening in 64 cases, bronchiectasis in 20 cases, bronchiole wall thickening in 42 cases, bronchiectasis in 11 cases, bronchiectasis in 11 cases, and inflammatory exudative lesions in 54 cases.In the mosaic sign, there were 38 cases with less fine lung texture in the area of decreased lung density, 20 cases with no obvious change, 20 cases with 30.8%, and 7 cases with slight thickening of 10.8%.The effective radiation agent was 1.08 卤0.65 m Sv.Conclusion the main CT signs of PIBO in children are mosaic sign, the thickening of the wall of the atmosphere and bronchiole, its high incidence rate and diffuse distribution, which suggests that the immune mechanism may be involved in the pathogenesis of PIBO.The changes of bronchioles are of great significance for the diagnosis and clinical treatment of PIBO.
