Fig. 3From: Shortened duration whole body 18F-FDG PET Patlak imaging on the Biograph Vision Quadra PET/CT using a population-averaged input functionScatter plots of lesion Ki obtained using the IDIF versus lesion Ki obtained using the PIF scaled to the IDIF at 30–60 min p.i. (PIF _30) and the PIF scaled to the IDIF at shortened scan time intervals p.i. (PIF _40 and PIF _50). Dashed lines represent linear regression fits (with intercept set to (0.0)Back to article page
