Time-activity curves (TACs) for m18333-fasted (top) and m17156-fasted (bottom) mice. Time is displayed on a log scale. Input function 1 is the arterial blood TAC. Input function 2 is a TAC that combines the arterial blood TAC with the initial part of the blood-pool region of the left ventricle TAC that contains the peak. The blood-pool region of the left ventricle TAC was corrected for spillout effects using a recovery coefficient of 0.5.
