Influence of the correction for blood cell uptake on FDG kinetic modeling in mouse brain cortex. (A) K1, (B) k2, (C) k3, (D) KFDG. V1131 to V1136 are scan numbers. IFs were calculated according to Equation 3 (black bars; IF exper, Wu et al. ; for mice), Equation 4 (magenta; IF exper, Weber et al. ; for rats), with a constant scaling factor (light brown; IF exper, scaled 1.165) or blood radioactivity was used as IF (dark brown).
