Visualization and Material-Based Differentiation of Lodged Projectiles by Extended CT Scale and the Dual-Energy Index

This study uses real forensic cases to demonstrate that—depending on the degree of deformation—a detailed visualization of lodged projectiles using ECTS can provide useful information regarding the ammunition used and allows accurate caliber measurements. Independent from the degree of deformation, the in situ classification of bullets, even fragmented bullets, according to their metallic components is feasible by dual-energy index (DEI) calculations. The assessment of a lodged projectile with CT images provides useful information on the case; thus, a close examination of lodged projectiles or bullet fragments should be a part of the overall radiological examination for cases of penetrating gunshot wounds.Graphical abstract
