Concentration of 18F-SP203 and its percentage composition in arterial plasma. (A) Average concentration (%SUV) of 18F-SP203 in arterial plasma is plotted vs. time after injection. Value for 10 min is shown on both graphs, which differ in range of y-axis. (B) Percentage composition of plasma that represents parent radioligand (●) and radiometabolites (○) are plotted vs. time after injection. (C) This radiochromatogram illustrates plasma composition at 45 min after injection of 18F-SP203. One major radiometabolite (A; 92%) eluted in void volume of column followed by minor one (B; 1%) and parent 18F-SP203 (7%). Radiometabolites A and B are both more polar than parent. Conc = concentration.
