Virtopsy Computed Tomography in Trauma: Normal Postmortem Changes and Pathologic Spectrum of Findings

Area of Science:

• Forensic radiology
• Medical imaging in forensics

Background:

• Traditional forensic autopsy is time-consuming and invasive.
• Virtopsy (virtual autopsy) is an emerging technique using imaging to supplement forensic examinations.
• Computed tomography (CT) and magnetic resonance imaging (MRI) are key virtopsy modalities.

Purpose of the Study:

• To evaluate the utility of virtopsy CT in forensic investigations.
• To highlight the role of virtopsy CT in trauma cases.
• To discuss the interpretation challenges of postmortem CT scans.

Main Methods:

• Virtopsy CT involves a pan-body noncontrast CT scan performed postmortem.
• The technique aims to provide an overview of injuries and suggest causes of death.
• Comparison with traditional autopsy findings is implied.

Main Results:

• Virtopsy CT effectively detects craniofacial, cerebral, thoracic, and osseous injuries in trauma cases.
• It can provide an overview of injuries and suggest potential causes of death.
• The technique has the potential to reduce forensic autopsy duration and necessity.

Conclusions:

• Virtopsy CT is a valuable adjunct to traditional forensic autopsy, particularly in trauma.
• Accurate interpretation requires awareness of both pathological findings and postmortem decomposition changes.
• Understanding these changes is crucial to avoid misinterpretation and accurately determine the cause of death.
