Single-Phase Surrogate for True Non-Contrast Liver CT Using 190-keV Monoenergetic Imaging on Photon-Counting CT: Implications for Hepatic Steatosis Assessment.
RATIONALE AND OBJECTIVES To evaluate whether 190-keV virtual monoenergetic imaging (VMI) using photon-counting detector CT (PCD-CT) can serve as a surrogate for true non-contrast (TNC) in hepatic steatosis quantification and to compare its attenuation agreement with virtual non-contrast (VNC). METHODS Forty-nine pati...
