Results for the visibility of the focal liver lesions in the biopsy images for conventional images (CIs), virtual monoenergetic (VMI) images at 40–200 keV and virtual non-contrast images (VNC) are shown. Results for each patient (1–20) are presented individually as well as the median of all patients. Highest ratings regarding visibility of the lesions are highlighted in bold. For patient #11 and #19, no rating is highlighted as almost all ratings were identical
