Low-contrast hyper-attenuating FLL (arrow) in the left lateral segment of the liver with different body phantom sizes. On polychromatic iDose4 image, as the phantom size is bigger ([a] small and [b] large), the low-contrast FLL is less visible. When adjusting the image for a low keV level (56 keV) VMI on large size phantom (c), the FLL visibility is markedly improved compared polychromatic iDose4 images.
