Example of the tail of the time-activity curves from imaging-derived input functions at different locations and different reconstruction settings for [¹⁸F]FDG (A) and for [¹⁸F]DPA-714 (B) (AA: Ascending Aorta, DA: Descending Aorta, LV: Left Ventricular Cavity, it: iterations, gauss: Gaussian post-filtering, mat440: matrix 440 × 440, abs: absolute scatter correction method). All IDIFs were extracted using AA location except for EARL2_DA and EARL2_LV
