The comparison of subject 1 input function obtained using full arterial sampling and average POP-IFs. Comparison of subject 1 input function obtained using full arterial sampling (black curve) and average POP-IF (red curve) obtained using a) seven discrete samples up to 65 min (POP-IF7), b) five discrete samples (POP-IF5) and c) three discrete samples (POP-IF3). As expected, the population-based input functions failed to reproduce the true initial peak height. However, the curves superimposed well after 2 min post injection, where the POP-IF are based on the individual blood measures.
