Targeted post-mortem computed tomography cardiac angiography: proof of concept

Area of Science:

• Forensic Pathology
• Medical Imaging
• Cardiovascular Imaging

Background:

• Near virtual autopsy (NVA) utilizes advanced imaging like multi-detector computed tomography (MDCT) and magnetic resonance imaging (MRI).
• A major limitation of NVA is the insufficient detail of coronary arteries, hindering its potential to replace conventional invasive autopsies.
• Current post-mortem imaging lacks a cost-effective, high-throughput solution for detailed coronary artery visualization.

Purpose of the Study:

• To present a proof-of-concept for a novel, minimally invasive cardiac angiography technique.
• To enable detailed, in situ imaging of coronary arteries for post-mortem examinations.
• To support the advancement of near virtual autopsy by overcoming imaging limitations.

Main Methods:

• Development of a simple, quick, and cost-effective manual, targeted in situ post-mortem cardiac angiography method.
• Utilizing a minimally invasive approach for cadaveric imaging.
• Integration with multi-detector computed tomography (MDCT) for high-throughput analysis.

Main Results:

• The described method provides a practical solution for detailed coronary artery imaging in post-mortem examinations.
• Demonstrates feasibility for use in both permanent and temporary mortuary settings.
• Offers a cost-effective approach to enhance virtual autopsy capabilities.

Conclusions:

• The developed cardiac angiography technique is a viable method to improve coronary artery visualization in near virtual autopsies.
• This minimally invasive approach addresses a critical gap in current post-mortem imaging capabilities.
• Facilitates higher throughput and more detailed forensic analysis using MDCT.
