Dommaraju S, Nakhaei M, Zhang D, et al. - This study was undertaken to investigate the effect of single-energy metal artifact reduction (SEMAR) algorithm utilizing retrospective adaptive thresholding in reducing metal artifacts in the abdomen and pelvis. Researchers performed a prospective institutional review board–approved, Health Insurance Portability and Accountability Act–compliant study including a total of 90 patients with various metals (n = 97) on CT of abdomen and pelvis (Canon Medical, Aquilion ONE and PRIME) scanned 07/2017–09/2018 with SEMAR retrospectively used. They assessed density in the near and far field to the metals. The data exhibit that by high- and low-density metals, SEMAR retrospective algorithm with adaptive thresholding subjectively and objectively decreased near-field artifacts generated.
