Whole-body post mortem computed tomography angiography: technical notes.

Area of Science:

• Forensic Pathology
• Medical Imaging
• Radiology

Background:

• Post mortem CT (PMCT) is standard in some Czech forensic departments.
• Global forensic science necessitates advanced imaging integration.
• PMCTA offers enhanced precision and objectivity in forensic diagnostics.

Purpose of the Study:

• To present technical notes on developing whole-body PMCTA in forensic practice.
• To assess the diagnostic efficacy of PMCTA compared to conventional autopsy.
• To evaluate different perfusion media for PMCTA.

Main Methods:

• Routine native CT examinations since 2015.
• Application of whole-body PMCTA in over thirty cases.
• Comparative study of polyethylene glycol, saline, and paraffin oil as perfusion media.

Main Results:

• PMCTA is suitable for most corpses, excluding those with advanced decomposition or extensive injuries.
• Highest diagnostic yield observed in cases of suspected gastrointestinal bleeding and vascular pathologies, particularly large vessel lesions.
• Institutional support was crucial for adopting the technique.

Conclusions:

• Whole-body PMCTA is a valuable addition to forensic investigation workflows.
• The technique significantly improves diagnostic precision and objectivity.
• PMCTA protocols can be adapted for various forensic department needs.
