This is the first of a series of 4 white papers that represent Expert Consensus Documents
developed by the Society of Computed Body Tomography and Magnetic Resonance …

Over the past decade, computed tomographic (CT) urography has emerged as the primary
imaging modality for evaluating the urinary tract in various clinical settings, including the …

Dual-energy CT (DECT) is a tremendous innovation in CT technology that allows creation of
numerous imaging datasets by enabling discrete acquisitions at more than one energy level …

Purpose To assess virtual non-contrast (VNC) images obtained on a detection-based
spectral detector CT scanner and determine how attenuation on VNC images derived from …

Computed Tomography Urography (CTU) is a multiphase CT examination optimized for
imaging kidneys, ureters, and bladder, complemented by post-contrast excretory phase …

Background Dual-energy (DE) CT allows reconstruction of virtual noncontrast (VNC) images
from a single-phase contrast agent–enhanced examination, potentially reducing the need …

Renal masses are increasingly detected in asymptomatic individuals as incidental findings.
An indeterminate renal mass is one that cannot be diagnosed confidently as benign or …

Purpose To compare attenuation measurements and image quality of virtual unenhanced
phase (VUP) images with those of conventional true unenhanced phase (TUP) images on …

Intravenous urography has been widely used for the evaluation of upper tract urothelial
carcinoma. However, computed tomography urography presently has a higher diagnostic …

Purpose To assess whether virtual non-contrast (VNC) images derived from contrast dual-
layer dual-energy computed tomography (DL-DECT) images could replace true non-contrast …
