Mean ± SD of metabolite-corrected input function and unmetabolized11C-TMSX fraction. (A) Mean ± SD of metabolite-corrected input function for four healthy human subjects. The inserted graph corresponds to early data. The unit of plasma data was SUV [concentration/(injected dose/body weight)]. (B) Mean ± SD of unmetabolized 11C-TMSX fraction and mean of fitted curve for four healthy human subjects. The parent fraction was fitted using a sum of exponentials. Open and closed circles correspond to test and retest scans, respectively. Error bars show the standard deviation.
