Research Progress on Postmortem Changes of Computed Tomography Imaging Characteristics on Corpses

Area of Science:

• Forensic Radiology
• Postmortem Imaging
• Medical Imaging

Background:

• Postmortem changes begin immediately after death.
• These changes alter the body's structure and imaging characteristics.
• Computed tomography (CT) imaging can be affected by postmortem changes, leading to potential misinterpretations.

Purpose of the Study:

• To systematically summarize CT imaging characteristics of postmortem changes.
• To enhance the application of virtopsy in forensic pathology.
• To provide a reference for identifying injuries, diseases, and normal postmortem changes.

Main Methods:

• Systematic review of literature on postmortem CT imaging.
• Analysis of characteristic changes observed in CT scans of deceased individuals.
• Correlation of imaging findings with known postmortem processes.

Main Results:

• Postmortem changes present distinct patterns on CT scans.
• These changes can lead to false positives and false negatives in injury and disease identification.
• Specific CT findings are associated with different stages of decomposition and postmortem intervals.

Conclusions:

• Accurate interpretation of postmortem CT requires understanding of postmortem changes.
• Virtopsy, utilizing CT imaging, can be a valuable tool in forensic investigations.
• This systematic summary aids forensic pathologists in differentiating postmortem changes from antemortem pathology.
