Text: Compared with two Iopromide 370 subgroups, Iomeprol 270 subgroups showed no significant difference in CT attenuation (576. 63 95. 50 vs. 569. 51 118. 93 for BMI < 25 kg/m (2), p = 0. 647 and 394. 19 68. 09 vs. 383. 72 63. 11 for BMI 25 kg/m (2), p = 0. 212), noise (in various anatomical regions of interest) and image quality (3. 5 vs. 4. 0, p = 0. 13), but significantly (0. 41 0. 17 vs. 0. 94 0. 45 for BMI < 25 kg/m (2), p < 0. 001 and 1. 14 0. 24 vs. 2. 37 0. 69 for BMI 25 kg/m (2), p < 0. 001) lower radiation dose, which reflects dose saving of 56. 4 % and 51. 9 %, respectively.
