New bone post-processing tools in forensic imaging: a multi-reader feasibility study to evaluate detection time and...

Area of Science:

• Forensic radiology
• Medical imaging analysis

Background:

• Accurate rib fracture assessment is crucial in forensic investigations.
• Traditional autopsy methods can be time-consuming and may miss subtle fractures.

Purpose of the Study:

• To evaluate novel post-processing CT imaging tools for rib fracture detection in forensic cases.
• To analyze the impact of these tools on detection time and diagnostic accuracy.

Main Methods:

• Thirty autopsy cases (20 with fractures, 10 without) underwent whole-body CT scans.
• CT images were analyzed using standard transverse views (modality A), axial rib labeling (modality B), and rib cage unfolding visualizations (modality C, 'eagle tool').
• Three blinded radiologists assessed all cases across different modalities, comparing results to autopsy findings.

Main Results:

• CT imaging showed better agreement with a CT consensus read than autopsy alone.
• The 'eagle tool' (modality C) significantly reduced rib fracture detection time.
• While slightly less precise than other modalities, the 'eagle tool' proved efficient for initial screening.

Conclusions:

• Advanced CT post-processing software enhances sensitivity and specificity for rib fracture detection compared to autopsy.
• The 'eagle tool' is a valuable, user-friendly option for preliminary rib fracture screening in forensic pathology.
• These tools can aid forensic pathologists by optimizing detection time and accuracy.
