Abstract

PURPOSE: To compare image quality obtained in phantoms with virtual monochromatic spectral (VMS) imaging with that obtained with conventional 120-kVp computed tomography (CT) for a given radiation dose. MATERIALS AND METHODS: Three syringes were filled with a diluted contrast medium (each syringe co...
