Radiological evaluation of hyperdense rim sign. First, the cutaneous wound is detected on axial (A), coronal (B) and sagittal (C) views. Then, 2 of the 3 views are used to adjust for cutaneous plane obliquity (dotted lines in A and B) and create a multiplanar reconstruction tangent to the cutaneous wound (D). In order to label the Hyperdense Rim Sign, structures that are considered as bone (arrow in E) are not taken into account. After removing bone areas (blue area in F), only remaining hyperdensities are considered (yellow area in F). Hyperdense Rim Sign is confirmed only if hyperdense region is extended at least over 2/3 of the wound

Post-mortem computed tomography (PMCT) is an increasingly utilized tool in forensic medicine for evaluating head gunshot injuries. Vault bevelling sign, when present, provides information regarding entry and exit wounds; when absent, identifying wound type on PMCT remains challenging. A cutaneous hyperdense ring, described in an animal study by Jun...

In this paper, we present a forensic perspective on classifying gunshot wound patterns using Deep Learning (DL). Although DL has revolutionized various medical specialties, such as automating tasks like medical image classification, its applications in forensic contexts have been limited despite the inherently visual nature of the field. This study...
