目的：我们试图在非创伤性死亡病例中获得死后肺部计算机断层扫描（PMCT）图像，并描述其结果，以区分通常的死后发现与特定胸部死亡原因。材料与方法：我们的研究对象是1993年1月至2001年12月期间，共有150例连续非创伤性心肺骤停病例在抵达后2小时内接受CT检查。回顾性分析了肺的PMCT图像和成像结果的频率（依赖密度、磨玻璃衰减（GGA）、实变、胸腔积液和气管内（或支气管内）空气缺损）。对其中16起案件进行了尸检。结果如下：死亡原因和依赖密度、GGA、实变、胸腔积液和气管内积液的频率百分比（或支气管内）空气缺损：91例急性心力衰竭（AHF）（69，66，24，11，14%），主动脉夹层23例（57，39，4，52，0%），肺炎11例（18、92、100、45、27%）、23例其他指定病例（52，30，13，17，9%）和2例未指明的病例（0，0，0，50，0%），[各自的总频率百分比为（60，57，25，21，12%）]。尸检证实AHF病例PMCT上的GGA对应于肺水肿。结论：当。肺PMCT显示除依赖密度外无其他阴影，需要进一步分析以检测死因。(C)2003爱思唯尔爱尔兰有限公司保留所有权利。
Purpose: We attempted to obtain postmortem computed tomographic (PMCT) images of the lung in cases of non-traumatic death and describe the results to distinguish usual postmortem findings from those of specific thoracic causes of death. Materials and methods: Our subjects were a total of 150 consecutive non-traumatic cases with cardiopulmonary arrest on arrival who were examined by CT within 2 h after certification of death between January 1993 and December 2001. PMCT images of the lung and the frequency of imaging findings (dependent density, ground glass attenuation (GGA), consolidation, pleural effusion, and endotracheal (or endobronchial) air defect) were retrospectively reviewed. Autopsy had been conducted in 16 of the cases. Results: The causes of death and frequency percentages of dependent density, GGA, consolidation, pleural effusion, and endotracheal (or endobronchial) air defect were: 91 cases of acute heart failure (AHF) (69, 66, 24, 11, 14%), 23 cases of aortic dissection (57, 39, 4, 52, 0%), 11 cases of pneumonia (18, 92, 100, 45, 27%), 23 other specified cases (52, 30, 13, 17, 9%), and two unspecified cases (0, 0, 0, 50, 0%), [total respective frequency percentages were (60, 57, 25, 21, 12%)]. Autopsy confirmed that GGA on PMCT in AHF cases corresponded to pulmonary edema. Conclusion: When. PMCT of the lung shows no other shadows than dependent density, further analysis is necessary to detect the cause of death. (C) 2003 Elsevier Ireland Ltd. All rights reserved.
