Metal artifact reduction for intracranial projectiles on post mortem computed tomography

3D reconstructions, 4D imaging and postprocessing with CT in musculoskeletal disorders: Past, present and future

“…Metal artifact reduction (MAR) techniques reduce the metal artifacts in all three directions, and they can be used synergistically with post-processing tools to provide high quality images [23][24][25][26]. Wide-detector CT scans provide temporal uniformity of the entire volume studied and reduce motion artifacts [27,28].…”

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

“…Although metal artefact reduction algorithms are routinely applied to improve the image quality and reduce the bright and dark streaks caused by metallic objects, these reconstruction algorithms do not improve the visualisation of a lodged bullet. 8,9 For this purpose, the standard CT scale has to be extended. Otherwise, voxels including materials with a radiodensity above the upper range of the standard CT scale, such as metals, are assigned the maximum (standard) greyscale value (CT number) of þ3071 HU.…”
