Comparison of Dose Estimates of Methods 2–4 Against Conventional Method 1 Dose Estimates for Patients Grouped by Prior Treatments and Abnormal Renal Function
| Patient group | Conventional, method 1 | Blood only, method 2 | Camera only, method 3 | 48-h camera only, method 4 |
| PT+ and AF− (n = 26) | 12 ± 9 cGy/GBq | 12 ± 9 cGy/GBq, P = 0.63 | 13 ± 8 cGy/GBq, *P = 0.03 | 13 ± 11 cGy/GBq, P = 0.76 |
| PT− and AF− (n = 22) | 22 ± 17 cGy/GBq | 21 ± 16 cGy/GBq, P = 0.22 | 23 ± 17 cGy/GBq, P = 0.25 | 14 ± 12 cGy/GBq, *P = 0.002 |
| PT− and AF+ (n = 17) | 29 ± 9 cGy/GBq | 30 ± 10 cGy/GBq, P = 0.54 | 27 ± 11 cGy/GBq, P = 0.17 | 20 ± 13 cGy/GBq, *P = 0.0008 |
| PT+ and AF+ (n = 6) | 34 ± 13 cGy/GBq | 35 ± 11 cGy/GBq, P = 0.51 | 30 ± 14 cGy/GBq, P = 0.11 | 29 ± 29 cGy/GBq, P = 0.52 |
↵* P < 0.05 vs. method 1.
PT+ = patients who had prior 131I treatment; AF− = patients with normal renal function; PT− = patients who did not have prior 131I treatment; AF+ = patients with abnormal renal function.
