A Comparative Study of Intravital CT and Autopsy Findings in Fatal Traumatic Injuries.

Area of Science:

• Forensic Pathology
• Radiology
• Trauma Medicine

Background:

• Traumatic injuries cause millions of deaths globally each year.
• Computed tomography (CT) is crucial for diagnosing trauma severity and extent.
• Autopsy remains the gold standard for definitive post-mortem examination.

Purpose of the Study:

• To evaluate the accuracy and reliability of antemortem CT scans for forensic trauma detection.
• To compare CT findings with autopsy results in trauma fatalities.
• To identify the limitations of CT in diagnosing specific types of traumatic injuries.

Main Methods:

• A retrospective-prospective study of 510 trauma deaths.
• Comparison of antemortem CT scan findings with autopsy results.
• Review of autopsy protocols, photographic documentation, and CT interpretations by clinical radiologists.

Main Results:

• Initial comparison showed a 75.3% correlation between CT and autopsy findings.
• Discrepancies were noted in 24.7% of cases.
• Re-evaluation by radiologists reduced the discrepancy rate to 17% for injuries missed by initial CT interpretation.

Conclusions:

• CT is effective for diagnosing head injuries and bone fractures but has limitations with cranial base fractures.
• Autopsy excels at detecting minor injuries to organs and soft tissues.
• CT is a valuable adjunct to autopsy in forensic trauma assessment.
