摘　　要：目的探讨百草枯中毒的胸部X线和CT表现特征。方法对21例百草枯中毒病人的X线胸片和CT资料进行回顾性分析。结果21例百草枯中毒肺部X线和CT表现随中毒时间变化而不同。≤7d,17例表现为肺纹增多,14例毛玻璃样改变,2例肺实变,肺间质纤维化、胸腔积液、纵隔气肿及心脏增大各1例;7～14d,肺纹理增多、肺实变及肺纤维化各4例,肺毛玻璃样改变3例;≥14d,肺间质纤维化4例,支气管扩张3例,肺纹理增多2例。结论胸部X线平片、CT对观察该病的发展、演变及估计预后、确定治疗方案均有重要意义。Objective To describe X - ray and CT findings of lung in paraquat poisoning. Methods CT and X - ray data of chest in 21 patients with paraquat poisoning were retrospectively analyzed. Results X - ray and CT findings of lung were varied with different time. ≤7 d,there were mainly increase of lung marking in 17 cases,ground -grass attenuation in 14 cases and consolidation in 2 cases. 7 - 14 d,increase of lung marking,consolidation and pulmonary fibrosis each could be seen in 4 cases,and 3 cases with ground - grass attenuation. ≥ 14 d,there were pulmonary fibrosis in 4 cases,bronchiectasis in 3 cases,increase of lung marking in 2 cases. Conclusion Chest plain X - ray film and CT are of important value in observing the evolution,evaluating the prognosis and guiding the treatment project for the patients with paraquat poisoning.
