Results of numerical simulations for percentage error. Panel A, v p . Panel B, Ktrans. Panel C, v e . Panel D, K ep . Red dashed line, results for the same time resolution (STR) sampling scheme. Green solid line, results for the different time resolution (DTR) sampling scheme implemented in SHILO (AIF time resolution 1.6 s). Blue dash dotted line, results for the second different time resolution (DTR) sampling scheme with AIF time resolution 0.8 s.
