The potential of high-Z contrast media for vessel visualization near metal implants: a photon-counting detector CT phantom study with virtual monoenergetic images and iterative metal artifact reduction
High-Z contrast media provide superior vessel contrast compared to iodine near metal implants in PCD-CT, both at low VMI energy with holmium and at high VMI energy with tungsten and bismuth, where metal artifacts are additionally reduced. Under metal artifact conditions, vessel contrast can be further improved by applying IMAR.
