Fig. 4

A comparison between reduced-dose computed tomography (CT) with deep DLR images, with and without CE-boost. Although, CE-boost markedly increased CT attenuation (blue arrow) even at reduced dose levels using SilverBeam filter, spotty high-density artifacts (red arrows) were observed in the bowel. These artifacts resulted from misregistration between non-contrast and CE images, exacerbated by motion artifacts. DLR deep learning reconstruction; CE contrast-enhanced.
