Akimova 2010.

Methods	Double‐blind, randomised, longitudinal PET study using radioligand [11C]DASB
Participants	18 patients
Interventions	10 mg/d escitalopram or 20 mg/d citalopram, i.e. equal doses of the enantiomer S‐Citalopram
Outcomes	Serotonin transporter availability in the unmedicated state and SERT occupancy after a single‐dose and later after the first 3 weeks of treatment with SSRIs. The Hamilton Depression Rating scale (HAM‐D, 17 items) was assessed at the screening visit and before each PET scan.
Notes	Radioligand [11C]DASB is a new, highly selective PET radiotracer that shows a high affinity for serotonin transporter
