Figure 6
Scatter plot of the relationship between body weight (BW; kg) and tumor liver contrast (TLC) at arterial phase (AP). Protocol-D showed closer linear approximation between BW and TLC between 4 protocols, because R2 of Protocol-D was closer to 1 than those of Protocols A, B, C. Protocol-D showed significant inverse relationship between BW and TLC (P = 0.0053). HU; Hounsfield unit.
