BACKGROUND Computerized tomography (CT) is finding increased use in forensic medicine. In this article we present our experience with CT in medico legal deaths. METHODS This is a retrospective investigation of 150 deceased individuals who were CT-scanned and autopsied. The CT-scanning was performed and interpreted by a specialist in forensic medicine. The CT-scanning and the autopsy were performed independently by two different physicians. RESULTS In 9% of the cases, important findings by the CT-scanning were overlooked at the autopsy, and in 51% important findings by the autopsy were not found by the CT-scanning. The cause of death could be established by CT-scanning in 30%, by autopsy in 72% and by toxicology in 21% of the cases. CT-scanning was most useful in cases of traumatic death. CONCLUSIONS CT is rarely a substitute for autopsy, but may contribute with important new information in many cases such as identifications (including mass-disasters), gunshot wounds and traffic accidents. CT provides documentation in digital form that is easily stored and copied, permits review by others and provides pictures that may be more suitable for presentation in court than autopsy photos. CT may be helpful in medico legal external examinations (inquests) in the process of selecting cases for autopsy.
