摘　　要：目的:探讨百草枯中毒的胸部CT影像表现特征。方法:回顾分析2003年1月—2013年2月10例百草枯中毒患者的胸部CT资料。结果:10例患者中,2例(20%)轻度中毒患者胸部CT检查为阴性,8例(80%)患者胸部CT检查为阳性。8例胸部CT检查阳性的患者中,4例中中毒患者的早期表现为两肺下叶磨玻璃影,后期逐渐发展为两肺间质纤维化;另4例重度中毒且死亡患者的早期表现为两肺肺纹理增多及磨玻璃影,中期逐渐发展为两肺片状实变影,晚期出现胸腔积液、肺水肿、心包积液。结论:胸部CT检查对百草枯中毒患者的诊断和预后有重要价值。Objective：To investigate the CT findings of chest after paraquat poisoning.Methods：The chest CT finds in ten patients with paraquat poisoning were retrospectively analyzed from January 2003 to February 2013.Results：Amone 10 patients,two （20％） with light paraquat poisoning had no CT abnormal findings,and eight （80％）had CT abnormal findings.Amone the 8 patients,four cases showed ground glass opacity in the early stage of poisoning and pulmonary fibrosis in the late stage of poisoning,and other four cases showed increase of lung markings and ground-glass opacity in the early stage of poisoning,pulmonary consolidation in the middle stage of poisoning,pleural effussion,pulmonary edema and pericardial effusion in the late stage of poisoning.Conclusions：Chest CT examination is useful for diagnosis and prognostic evaluation for the patients with paraquat poisoning.
