Epub 2012 Aug 11.PURPOSE: [(18)F]SP203 (3-fluoro-5-(2-(2-([(18)F]fluoromethyl)-thiazol-4-yl)ethynyl)benzonitrile) is an effective high-affinity and selective radioligand for imaging metabotropic 5 receptors (mGluR5) in human brain with PET. To provide a radioligand that may be used for more than one scanning session in the same subject in a single day, we set out to label SP203 with shorter-lived (11)C (t (1/2) = 20. Read More
