Regional striatal DOPA transport and decarboxylase activity in Parkinson's disease.

Abstract

METHODS We measured blood-brain barrier transport and decarboxylation of 6-[18F]fluoro-L-DOPA (FDOPA) using PET in patients with Parkinson's disease (n = 7, 57 +/- 7 yr) and age-matched control subjects (n = 7, 60 +/- 6 yr). To visually present regional changes of FDOPA uptake in Parkinson's disease, we introduced maps of FDOPA uptake relative to occipital… (More)
