摘要
目的研究MSCT在百草枯中毒肺损伤中的影像学征象及其临床价值。方法回顾性分析26例百草枯中毒致肺损伤的MSCT影像学资料。结果中毒早期(1～3 d),部分轻症患者可不出现肺部异常改变;中、重度患者可显示为以肺通气增强、毛玻璃样密度为主的影像学特征,以中下肺野及肺叶外带为著。中期(4～7 d),主要表现为支气管血管束增粗伴支气管轨道征、肺实变及肺渗出性病变为主。中后期(>7 d),CT可显示病变呈迁延性改变,肺渗出实变、肺纤维化为主要影像学表现。结论 MSCT征象可反映百草枯中毒致肺部损伤的演变过程,对临床治疗及判断预后具有指导意义。
Objective To investigate the imaging feature of MSCT to lung impairment caused by pa- raquat poisoning. Methods The chest radiographic data of 26 patients suffering from paraquat poisoning were analyzed retrospectively. Results In the early period （ 1-3 d） ： some patients of mild sympotmes might have no abnormal lung changes;patients of medium and heavy symptoms showed hyperventilation and glass density,especially at the bottom or lateral of lungs. In the middle period （4-7 d ）, cases mainly presented bronchovaseular bundle thickening associated with the bronchial track sign,lung tissue lesion and pulmonary exudative lesions. In the late period （ 〉 7 d）, CT could show the persistent lesions, with pulmonary tissue change and fibrosis as the main imaging performance. Conclusion MSCT manifestations can show the pro- gression of paraquat poisoning induced pulmonary damage, which is instructive for the clinical treatment and the prognosis assessment.
