Postmortem computed tomography (CT) is being used more frequently in forensic medicine. This review discusses 100 deceased individuals who underwent CT scanning, as well as a standard autopsy. The CT scan was performed and interpreted by a forensic medicine specialist. In 11 cases, important findings discovered during the CT scan were not found at autopsy, and in 58 cases, important findings revealed at autopsy were not uncovered during the CT-scan. The cause of death could be established by the CT scan and external examination in 27%; by CT scan, external examination, and forensic chemistry in 32%; and by autopsy in 95% of the cases. CT scanning was most useful in cases of traumatic death. CT is rarely a substitute for autopsy, but may contribute important new information in cases such as identifications (particularly following mass disasters), battered children, gunshot wounds, traffic accidents, and air embolisms. CT provides documentation in digital form, which is easily stored and permits review by others. CT also provides pictures that may be more suitable for presentation in court than autopsy photos. CT scanning also would be helpful during a medicolegal external examination (inquest) in the process of selecting cases for autopsy.
尸检计算机断层扫描（CT）在法医学中的应用越来越频繁。本综述讨论了100名接受CT扫描以及标准尸检的死者。CT扫描由一名法医学专家进行并解读。在11例病例中，CT扫描发现的重要结果在尸检中未被发现，而在58例病例中，尸检揭示的重要结果在CT扫描中未被发现。27%的病例可通过CT扫描和外部检查确定死因；32%的病例可通过CT扫描、外部检查和法医化学确定死因；95%的病例可通过尸检确定死因。CT扫描在创伤性死亡病例中最有用。CT很少能替代尸检，但在身份鉴定（尤其是在大规模灾难之后）、受虐儿童、枪伤、交通事故和空气栓塞等病例中可能会提供重要的新信息。CT以数字形式提供文档，易于存储并允许他人查阅。CT提供的图片可能比尸检照片更适合在法庭上展示。在法医外部检查（死因调查）过程中选择尸检病例时，CT扫描也会有所帮助。
