Description:
A radioiodinated ligand that binds to muscarinic acetylcholine receptors was shown to distribute in the brain by a receptor-mediated process. With single-photon-emission imaging techniques, radioactivity was detected in the cerebrum but not in the cerebellum, whereas with a flow-limited radiotracer, radioactivity was detected in cerebrum and cerebellum. Single-photon-emission computed tomography showed good definition of the caudate putamen and cortex in man.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Eckelman, W C -- Reba, R C -- Rzeszotarski, W J -- Gibson, R E -- Hill, T -- Holman, B L -- Budinger, T -- Conklin, J J -- Eng, R -- Grissom, M P -- New York, N.Y. -- Science. 1984 Jan 20;223(4633):291-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6608148" target="_blank"〉PubMed〈/a〉
