Mean Values ± SD of Iodine Biokinetics in Whole Body and Blood and Absorbed Doses to Blood After rhTSH and THW
| rhTSH | THW | P | |
|---|---|---|---|
| Whole-body retention at 48 h (%) | 6.9 ± 5.7 (n = 32) | 14.0 ± 10.8 (n = 27) | 0.0018 |
| Whole-body residence time (h) | 17.3 ± 3.9 (n = 32) | 24.1 ± 7.8 (n = 27) | 0.0002 |
| Blood retention at 48 h (%) | 0.78 ± 0.78 (n = 33) | 1.79 ± 1.71 (n = 30) | 0.0011 |
| Blood residence time (h) | 2.34 ± 0.73 (n = 33) | 3.53 ± 1.63 (n = 30) | 0.0004 |
| Absorbed dose to blood (mGy/MBq) | (n = 32) | (n = 26) | <0.0001 |
| Standard method, vessel radius: 0.2 mm | 0.072 ± 0.017 | 0.107 ± 0.036 | |
| Standard method, vessel radius: 5 mm | 0.104 ± 0.026 | 0.158 ± 0.059 | |
| Refined method | 0.109 ± 0.028 | 0.167 ± 0.061 |
Reduced numbers of patients with whole-body and blood dose data are due to technical failures during whole-body measurements.
