Résumé
To evaluate the reproducibility of cerebral adenosine A Eight healthy male volunteers were enrolled. Dynamic 90 min PET scans were performed twice at the same time of the day to avoid the effect of diurnal variation. Subjects refrained from caffeine from 12 h prior to scanning, and serum caffeine was measured before radioligand injection. Arterial blood was sampled repeatedly during scanning and the fraction of the parent compound in plasma was determined. Total distribution volume (V Regional time-activity curves were well described by 2-TCM models. Estimation of V In this study, moderate test-retest reproducibility and large inter-subject differences were observed with [ UMIN000030040.
