Fluoxetine, a selective serotonin reuptake inhibitor (SSRI), has shown favorable effects in some children with autism. There are no previous studies evaluating the connection between clinical outcome and markers of clinical response to fluoxetine tre

Quantification of regional myocardial blood flow (rMBF) with first-pass magnetic resonance imaging (FP-MRI) requires two contrast agent injections (dual bolus technique), inducing error in the determined rMBF if the injections differ. We hypothesize

Background: Myocardial 123I-metaiodobenzylguanidine (MIBG) kinetics reflect the integrity and function of cardiac presynaptic sympathetic nerve terminals. Heart rate variability (HRV) is an indicator of cardiac sympatho-vagal balance. However, the fu

Background To date the involvement of dopamine system in neurobiology of panic disorder (PD) has been not investigated by imaging studies in humans. In this study, we evaluated the binding potential of dopamine transporter (DAT) in striatum of patien
