Fig. 2.
Case 2 shows hepatocellular carcinoma with major tumor venous thrombus (TVT). (A) The consensus contour is represented by the thicker red line. The arrows highlight a panelist’s contour whose variability was related to the poor alignment of the planning computed tomograph (CT) with the magnetic resonance image (MRI; see Fig. 5). (B) A comparison of the TVT on CT in arterial phase on left, venous phase in the middle, and MRI. Note that the TVT is better visualized in the venous phase than in the arterial phase.
