When forensic radiology meets ballistics – in vivo bullet profiling with computed tomography and autopsy validation: A case report

Impacto de las pruebas balísticas en la investigación de muertes violentas

“…Por lo tanto, la TC no debía ser la única herramienta utilizada para el perfilado de la bala, y la experiencia en el comportamiento de deformación de las balas pudo haber mejorado los resultados del perfilado. (Alves et al, 2020) Otro estudio seleccionado concluye que el uso de municiones ecológicas en la comisión de delitos con armas de fuego exige una respuesta rápida y oportuna por parte de las autoridades judiciales. De lo contrario, esta tecnología puede convertirse en un factor de impunidad al permitir decisiones judiciales equivocadas basadas en pruebas que no 129 contribuyen al esclarecimiento del caso y que alejan el proceso de la verdad y la justicia, valores superiores del proceso.…”

A review on the evolution and characteristics of post-mortem imaging techniques

“…The study showed that MSCT aided in the correct identification of all lethal wounds and had a 100% precision in the location of metallic fragments [65]. In a similar investigation, Valdes et al studied the use of PMCT followed by traditional autopsy and showed that post-mortem imaging can be used for the accurate measurement and profiling of bullets trapped in the body of living victims that cannot be extracted through surgery [16]. 4.7 Infection -The use of post-mortem imaging has proven to be a valuable tool for the examination of suspected infections.…”

“…Currently, PMCT has proven to be a valuable technique for the detection of radio-opaque objects and the identification of traumatic processes such as blunt force or haemorrhage, and especially in osseous lesions; when compared to traditional autopsy [10,[16][17][18][19][20]. However, this technique shows a limited visualization of soft-tissue, making it unsuitable for the study of non-traumatic deaths, such ischaemic heart disease or pulmonary embolism [20].…”

Lodged bullets on computed tomography: Three classification procedures for the virtual investigation of bullets or their fragments that cannot be recovered from the living patient

“…Distance-measuring tools provided by any standard visualisation software can be used to investigate the bullet dimension in situ. 7,11,19 Since CT data allow the rotation of a captured object on the screen, a lodged bullet can be easily aligned to its short axis and long axis for measurements of the calibre and size, respectively. Reconstructions with small voxels improve the accuracy of the measured results.…”
