Figure 2

The mean contrast medium dose used in the three weight-based subgroups (≦50 kg, >50 kg and <65 kg, and ≧65 kg) were 62.87, 77.17, and 94.05 ml, respectively, in G1 and 71.38, 88.03, and 106.92 ml, respectively, in G2. There was statistical difference between the subgroups of the same weight range in G1 and G2.
