PET imaging of central 5-HT2A receptors with carbon-11-MDL 100,907.

Abstract

This preliminary study suggests that [11C]MDL 100,907 is a suitable PET radioligand for studies on 5-HT2A receptors in man. The high selectivity of MDL 100,907 represents a major advantage as compared to presently available radioligands with poor selectivity. Thus, [11C]MDL 100,907 is recommended in the future for PET studies in healthy subjects and schizophrenic patients, including the determination of drug-induced 5-HT2A receptor occupancy.
