Summary
Postmortem computed tomography (CT) is a useful complementary tool to autopsy for determining cause of death. While CT excels at detecting certain findings, autopsy remains crucial for others.
Area of Science:
- Forensic Medicine
- Radiology
- Pathology
Background:
- Autopsy is the traditional method for determining cause of death.
- Advancements in medical imaging offer potential for non-invasive postmortem examination.
Purpose of the Study:
- To evaluate the diagnostic accuracy of postmortem computed tomography (CT) compared to traditional autopsy.
- To identify the strengths and limitations of CT in postmortem investigations.
Main Methods:
- Twenty-seven cadavers underwent sequential cranial and helical CT scans of the neck, thorax, and abdomen.
- Subsequent autopsy with histomorphologic examination of specimens was performed.
- Findings from CT, autopsy, and histology were systematically compared by radiologists and a forensic medicine specialist.
Main Results:
- Concordant findings explaining cause of death between CT and autopsy in 19 out of 27 cases.
- CT alone identified intracranial, intraspinal, and intracardiac gas accumulations (n=12).
- CT demonstrated diagnostic challenges in assessing pneumonic infiltrations (n=16) and pulmonary edema (n=21).
Conclusions:
- Postmortem CT is a valuable and complementary diagnostic method to autopsy.
- CT can effectively detect specific postmortem findings, aiding in cause of death determination.
- Integration of CT with autopsy enhances the comprehensiveness of postmortem examinations.
