Noise reduction to decrease radiation dose and improve conspicuity of hepatic lesions at contrast-enhanced 80-kV hepatic CT using projection space denoising.

Abstract

OBJECTIVE The purpose of this study was to investigate the combined potential of 80-kV CT and noise reduction using a projection space denoising algorithm to reduce radiation dose reduction or to improve the image quality of hepatic CT. MATERIALS AND METHODS Twenty patients with 56 liver lesions underwent dual-energy (80 and 140 kV) contrast-enhanced… (More)
