The rate of patients rated as “excellent or good” in the qualitative tumor conspicuity at arterial phase (AP). Regarding qualitative evaluation, tumor conspicuity of hepatocellular carcinoma obtained in the subgroup of body weight (BW) > 60 kg was not discrepant with the quantitative evaluation of the aorta enhancement (Figure 4). In the subgroup of BW > 60 kg, tumor conspicuity in Protocol-D tended to be lower than those in the other groups, and the highest tumor conspicuity was obtained in Protocol-B, which included fixed duration with bolus tracking. In the subgroups of BW ≤ 50 kg, tumor conspicuity in Protocol-B tended to be lower than those in the other groups. Error bars indicate 95% confidence interval. -50; up to 50 kg of BW, 50 < −60; greater than 50 kg, up to 60 kg of BW, 60<; greater than 60 kg of BW.
