Can clinical CT data improve forensic reconstruction?

Area of Science:

• Forensic Radiology
• Medical Imaging
• Trauma Analysis

Background:

• Clinical forensic examinations are often deferred in severe trauma due to immediate medical priorities.
• Clinical computed tomography (CT) data frequently exists post-trauma, offering potential for retrospective forensic analysis.
• Limitations in clinical reports hinder detailed forensic interpretation of injuries.

Purpose of the Study:

• To assess the utility of clinical CT data for forensic reconstruction of injury events.
• To determine if dedicated forensic radiological review improves diagnostic yield over standard clinical reports.
• To evaluate the benefit of storing full CT datasets, including thin-slice reconstructions, for forensic purposes.

Main Methods:

• Prospective examination of clinical CT data from 15 polytrauma patients (head, thorax, abdomen).
• Reconstruction of 0.6-mm slices and 3D images for enhanced forensic analysis.
• Comparison of forensic findings from clinical reports versus dedicated follow-up readings.

Main Results:

• Additional traumatic findings were identified in 10 out of 15 patients during forensic review.
• Clinical reports often lacked sufficient detail on injury localization and morphology.
• Forensic reconstruction was possible from clinical reports in 7 cases, but required follow-up reading in 5 cases.
• Thin-slice reconstructions (0.6 mm) and 3D imaging significantly improved forensic diagnostic capabilities.

Conclusions:

• Clinical CT data is a valuable resource for forensic reconstruction in severe injury cases.
• Forensic radiological follow-up reading enhances the diagnostic benefit derived from clinical CT data.
• Utilizing thin-slice reconstructions and 3D imaging further optimizes forensic analysis of trauma events.
