Abstract
Background: Postmortem CT and multiphase postmortem CT angiography have been used for objective noninvasive documentation of body injuries, especially, in blunt trauma cases which are the most common injuries faced in forensic field practice. This study aims to assess the efficiency of PMCT and MPMCTA in diagnosis of blunt trauma deaths as an alternative technique to conventional autopsy. Methods: This prospective study examined 50 decedents presented to the legal institute of Hamburg University, alleged death due to blunt trauma by CT and\or MPMCTA. The resultant radiological findings are validated by conventional autopsy. Results: The study shows the low efficiency of PMCT in detection of soft tissue injuries and the superiority in detection and configuring of bony fractures and in detection and localization of air emboli and free air compared to autopsy. Multiphase PMCTA has a higher efficiency in detection of hemorrhage and in identifying the source of the bleeding compared to autopsy
