Globally, postmortem computed tomography is the most commonly used modality and is becoming increasingly available throughout the world. Forensic nurses working in association with coroners and medical examiners' offices, as well as mass fatality incidents, now need to update their knowledge base to understand these innovative techniques, the advantages and disadvantages to their use, and how they impact on medicolegal death investigation and the care of the deceased and bereaved. Using the example of the coroner system of England and Wales, this article provides a comparison between the traditional invasive autopsy and postmortem radiological alternatives and presents the impact postmortem radiology is now having on death investigation.
