摘　　要：目的：探讨百草枯中毒肺损伤的胸部影像学表现及临床价值.材料与方法：回顾性分析20例百草枯中毒患者的肺部影像表现及临床资料.结果：百草枯中毒肺部影像表现与检查时间、中毒剂量相关.早期（≤7d）以支气管血管束增粗及磨玻璃影为主;中期（8 ～14d）在磨玻璃影基础上出现肺实变影,同时伴发胸腔及心包积液;晚期（≥14d）以肺间质纤维化为主要表现.剂量小时肺部损害轻,剂量大时肺部损害重.结论：百草枯中毒肺部损害具有明确的影像特征,对判断肺损害、评估临床预后及制订治疗方案具有重要意义.Purpose： To explore the chest imaging and clinical value of lung injury in paraquat poisoning. Materials and Methods： A retrospective analysis of 20 cases of paraquat poisoning was studied with clinical data and pulmonary imaging manifestations. Results： Lung imaging of paraquat poisoning was related with inspection time and poisonus. In early stage （ ~〈 7d）, the ground glass opacity and consolidation was found on the periphery in the lung, accompanied by pulmonary hyperven- tilation; in the middle stage （7 - 14d） , the ground glass opacity and consolidation was gradually absorbed and narrow; in the late stage（ ~〉14d）, pulmonary interstitial damage was the main performance. The lung damage was slight with low dose, the damage was heavy with high dose. Conclusion： There was clear lung imaging findings in the paraquat poisoning. It has the great importance to the judgment of lung damage, assessment of clinical prognosis and treatment.
