Abstract
Objective The aim of this study was to evaluate the potential of iterative metal artifact reduction (IMAR) for the improvement of computed tomography (CT)–based position emission tomography (PET) attenuation correction in the vicinity of metal implants and compare it with dual-energy–based metal artifact reduction strategies. Methods A dedicated dental phantom was constructed consisting of a cylindrical tube filled with [18-F]FDG solution (5300...
