摘　　要：目的:分析探讨百草枯中毒致胸部损害的CT特征和诊断价值。方法:分析70例口服百草枯中毒致胸部损害的CT影像学资料。结果:早期(3 d内)主要表现为肺纹理增多、磨玻璃样改变、胸膜下线和心脏增大;早中期(4～7 d)主要表现为磨玻璃样改变、肺间质纤维化、胸膜下线、胸腔积液和心脏增大;中期(8～14 d)主要表现为肺纹理增多、磨玻璃样改变、肺间质纤维化、胸膜下线、胸膜增厚、心脏增大;中后期(15～28 d)主要表现为磨玻璃样改变、肺间质纤维化、胸膜下线、胸膜增厚;后期(>28 d)则以肺间质纤维化、胸膜下线多见。结论:百草枯中毒的胸部CT表现具有一定特征性,其影像学变化对病情发展及指导临床治疗具有重要意义。Objective：To analyse the imaging features and diagnostic value of CT examination of chest injury caused by poisoning of paraquat.Methods：Analysed 70 cases of CT imaging data of chest injury caused by oral administration of paraquat.Results：Early stage（within 3 days） the performances were characterized by increased lung markings,ground-glass-like changes,the assembly pleural line and cardiac enlargement;Early and mid-term stage（4 to 7 days） the main performances were the ground-glass-like change,pulmonary interstitial fibrosis,the assembly pleural line,pleural effusion and cardiac enlargement;Mid and late stage（15 to 28 days） the performances showed the ground-glass-like change,pulmonary interstitial fibrosis,the assembly pleural line and pleural thickening;Late stage（beyond 28 days） the performances were mainly characterized by te pulmonary interstitial fibrosis and the assembly line.Conclusion：The chest CT imaging of paraquat poisoning have a certain characteristic and the imaging changes and which play an important role in disease progression and guiding clinical treatment.
