Table 1 Comparison of delay in seconds between IDIFs derived from the descending aorta, brain arteries, brain veins, and tissue time activity curve (TTAC) for each subject in the adjustment group (P1 to P6)
From: Automated extraction of the arterial input function from brain images for parametric PET studies

P3 | 2 | 8 | 8 | 6 | 0 |
P4 | 2 | 8 | 8 | 6 | 0 |
P5 | 0 | 6 | 6 | 6 | 0 |
P6 | 0 | 6 | 6 | 6 | 0 |
