Postmortem computed tomography findings in suicide victims.

Area of Science:

• Forensic Radiology
• Medical Imaging
• Public Health

Background:

• Suicide is a significant cause of mortality in France, particularly among young adults.
• Common suicide methods include hanging, self-poisoning, and firearms.
• Autopsy is standard, but advanced imaging can supplement findings.

Purpose of the Study:

• To present the imaging features of various suicide methods observed via postmortem CT.
• To highlight the utility of postmortem CT in forensic investigations.
• To correlate imaging findings with specific modes of suicidal death.

Main Methods:

• Review of postmortem computed tomography (CT) imaging findings in deceased individuals.
• Correlation of imaging data with established autopsy findings and cause of death.
• Focus on characteristic features associated with hanging, firearm, drowning, and stabbing suicides.

Main Results:

• Postmortem CT effectively visualizes ligature marks, hyoid bone/thyroid cartilage fractures in hanging.
• CT identifies entry/exit wounds and projectile paths in firearm suicides, though internal trajectories can be challenging.
• Specific CT features are noted for drowning and stabbing, but utility is limited in self-poisoning and decomposed bodies.

Conclusions:

• Postmortem CT is a valuable tool for confirming suicide and excluding other causes of death.
• Imaging findings on CT correlate well with specific suicide methods like hanging and firearm use.
• Limitations exist, particularly in cases of self-poisoning, decomposition, and obscured internal injuries.
