Fig. 2.

Example patient from the Dataset. Arterial phase magnetic resonance images of a 58-year-old female patient with a 6.5 cm lesion in segment III of the liver in axial, coronal and sagittal planes (A) with corresponding manual liver (B) and tumor segmentations (C) of the two raters (rater 1: green, rater 2: blue). The lesion displays characteristics of a LI-RADS 5 lesion with nonrim arterial phase hyperenhancement (APHE), nonperipheral washout as well as an enhancing capsule on portal venous phase images. The calculated Dice Similarity Coefficient (DSC) between the segmentations of the two raters were 0.95 and 0.91 for the liver and tumor segmentations, respectively.
