Subhas N, et al. - The authors used an advanced metal artifact reduction (MAR) algorithm and standard filtered back projection (FBP) techniques to compare reader accuracy detecting lesions near hardware in a CT phantom model at different radiation exposures. Furthermore, they aimed to determine if radiation exposure could be decreased using MAR without compromising lesion detectability. Reader accuracy to detect lesions near hardware was improver due to MAR. In addition, compared with FBP in a CT phantom model, MAR allowed significant reductions in radiation exposure without compromising accuracy.
