Postprocessing metal artifact reduction techniques have been developed to decrease these artifacts, which has been proved to improve visualization of soft-tissue structures and increase diagnostic confidence. However, metal artifact reduction reconstruction introduces its own novel artifacts that can mimic pathology.MARmetal artifact reduction}, issn = {0195-6108}, URL = {https://www.ajnr.org/content/early/2019/10/03/ajnr.A6238}, eprint = {https://www.ajnr.org/content/early/2019/10/03/ajnr.A6238.full.pdf}, journal = {American Journal of Neuroradiology} }
