Electron Density Dual-Energy CT for Liver Metastasis Detection Compared with Conventional and Virtual Monoenergetic Images at 40 keV.
OBJECTIVE To estimate the contrast-to-noise ratio (CNR) of liver metastases with electron density (ED) derived from dual-energy computed tomography and compare it with conventional and virtual monoenergetic images at 40 keV in both the unenhanced and portal-dominant phases. METHODS This observational retrospective, s...
