Input function. Kinetics of total arterial plasma activity with and without correction for appearance of metabolites. Values for times less than 15 minutes are uncorrected measured values for one rat (early, full squares). Open squares represent the average of all measures of uncorrected %IA/g of plasma. Full triangles represent the average values corrected for the appearance of metabolites using percentages reported in table 3. Insert: zoom on early times.
