Photon-counting detector CT with virtual monoenergetic imaging and iterative metal artifact reduction for spinal fusion implants: optimal keV and combined benefits.
OBJECTIVES To evaluate the effectiveness of virtual monoenergetic imaging (VMI) and iterative metal artifact reduction (iMAR), alone and in combination, for reducing metal artifacts in postoperative CT scans of patients with spinal fusion, using a clinical photon-counting detector CT (PCD-CT) system. MATERIALS AND ME...
