11 C]N-methyl-SSR504734 was synthesized successfully using 11 C]CH3OTf with moderate radiochemical yield and ultrahigh specific radioactivity compared with previously reported GlyT1 imaging [19, 20, 23].
Pituitary cells treated with C-ATR and increasing concentrations of GHRF had reduced radioactivity compared with cells treated with C-ATR alone, which suggests that C-ATR and GHRF were competing for the same receptor.
Determination of the nanotube radioactivity by their direct addition to scintillation cocktail underestimated the nanotube radioactivity compared with combustion in a biological oxidizer, perhaps as a result of the absorption of beta emissions in nanotube bundles.
Despite the low branching fraction for Y and background radioactivity of some PET imaging systems, PET/CT imaging demonstrates better spatial resolution and image contrast than bremsstrahlung imaging (planar, SPECT, and SPECT/CT) [ 28, 44, 51] and clinically demonstrates improved detection of nontarget Y radioactivity compared with even bremsstrahlung SPECT/CT [ 14].
