Radiation Absorbed Dose to the Basal Ganglia from Dopamine Transporter Radioligand ¹⁸F-FPCIT

Figure 1

Dynamic ¹⁸F-FPCIT PET regions of interest data from basal ganglia fitted to extract residence times. Data from four regions of interest is presented (caudate and putamen on left and right hemispheres). A multiexponential curve fit to the right putamen data is also shown. Analytical area under the curve was obtained from this fitted curve and dose estimated using (1) (see text).
