Radioactive metabolites of the 5-HT1A receptor pet radioligand, [carbonyl-11C]way-100635, measured in human plasma samples

Measures of the percentage of radioactivity represented by parent radioligand in human plasma during PET experiments with [carbonyl-11C]WAY-100635 have been compared across 3 centres using 2 different methods. Test-retest reliability has been examined in 5 subjects in one centre. Good agreement is found for inter-centre and test-retest measures.
