1 The study was carried out in eight healthy human volunteers using as a tracer [11C]-physostigmine ([11C]PHY), an inhibitor of AChE. Carbon-11 acetylcholinesterase (Cartwright blood group) Homo sapiens
2 The study was carried out in eight healthy human volunteers using as a tracer [11C]-physostigmine ([11C]PHY), an inhibitor of AChE. Carbon-11 acetylcholinesterase (Cartwright blood group) Homo sapiens
3 [11C] PHY retention was higher in regions rich in AChE, such as the striatum (half-life, 35 min), than in regions poor in AChE, such as the cerebral cortex (half-life, 20 min). Carbon-11 acetylcholinesterase (Cartwright blood group) Homo sapiens
4 At later times (25-35 min postinjection), the cerebral distribution of [11C]PHY was typical of AChE activity: putamen-caudate > cerebellum > brainstem > thalamus > cerebral cortex, with a striatal to cortex ratio of 2. Carbon-11 acetylcholinesterase (Cartwright blood group) Homo sapiens
5 These results suggest that PET studies with [11C]PHY can provide in vivo brain mapping of human AChE and are promising for the study of changes in AChE levels associated with neurodegenerative diseases. Carbon-11 acetylcholinesterase (Cartwright blood group) Homo sapiens
