Injection parameters for both groups
| Injection parameters | Flow rate (ml s−1) | Peak flow rate (ml s−1) | IDR (gI s−1) | Main bolus volume (ml) | TIL (g) | Iodine per kg (g) | Peak pressure (psi) | |
|---|---|---|---|---|---|---|---|---|
| Group 1 | Low weight (40–75 kg) | 5.8 ± 0.3 | 6.3 ± 0.0 | 1.8 ± 0.0 | 89.5 ± 1.1 | 26.8 ± 0.3 | 0.43 ± 0.05 | 103 ± 18 |
| High weight (76–117 kg) | 5.7 ± 0.1 | 6.3 ± 0.0 | 1.8 ± 0.0 | 90.0 ± 0.3 | 26.9 ± 0.1 | 0.30 ± 0.03 | 106 ± 26 | |
| Group 2 | Low weight (40–75 kg) | 5.2 ± 0.4 | 5.8 ± 0.5 | 1.6 ± 0.1 | 54.6 ± 4.5 | 16.4 ± 1.4 | 0.26 ± 0.05 | 99 ± 17 |
| High weight (76–117 kg) | 6.1 ± 0.4 | 7.0 ± 0.5 | 2.0 ± 0.1 | 65.6 ± 4.7 | 19.7 ± 1.4 | 0.20 ± 0.00 | 122 ± 33 | |
| p-value | <0.01 | <0.01 | <0.01 | <0.01 | <0.01 | <0.01 | 0.33 | |
IDR, iodine delivery rate; TIL, total iodine load.
A significant decrease is seen for TIL, main bolus volume and iodine per kg for the individualized protocol vs standard protocol, in both low- and high-weight groups.
