火药燃烧致群体一氧化碳中毒的影像学表现及分析

目的：探讨火药燃烧致急性一氧化碳中毒肺、脑损伤的影像学表现．以提高诊断水平。方法：对37例一氧化碳中毒患者行胸部X线、头颅MRI检杏，并分析其影像学表现特点。结果：①急性肺损伤8例，表现为肺纹理增强、肺门浓密和肺部大片状阴影；②脑部损伤6例，表现为对称性海马、苍白球信号异常。结论：肺、脑是急性一氧化碳中毒极易受损的器官，肺损伤以肺水肿改变为主，脑损伤以海马、苍白球水肿、缺血、坏死改变为主。

Imaging manifestation and diagnosis of carbon monoxide poisoning caused by gunpower combustion

Objective:To study the imaging characteristics of brain and lung injury caused by acute carbon monoxide poisoning(COP) in gunpower combustion,in order to improve the accuracy of diagnosis.Methods: Carried on X-ray of chest and MRI of brain to 37 carbon monoxide posisoning sufferers,and analyzed the imaging characteristics.Results: ①The acute lung injury 8 cases,the performances were strengthened lung marking,thickened hilus of lung and large-scale shadow;②The brain injury 6 cases,the performances were the abnormal signal of hippocampus and globus pallidus.Conclusion: The lung and the brain are easiest damaged organs in the carbon monoxide poisoning.The principal change of the lung injury is pulmonary edema and the brain injury regarded edema,ischemia,putrescence of hippocampus and globus pallidus as principle.
