Vesicular monoamine transporter 2 (VMAT2) is a putative molecular target for the quantitative imaging of pancreatic beta-cell mass by PET. The VMAT2 PET tracer (11)C-dihydrotetrabenazine ((11)C-DTBZ) exhibits high pancreatic uptake that is reduced in

Introduction It has been previously reported that hippocampal dopamine D2/D3 receptors are involved in the regulation of verbal memory and learning in healthy volunteers. We tested this hypothesis further and studied whether cortical dopamine D2/D3 r

Positron emission tomography (PET) imaging of small striatal brain structures such as the ventral striatum (VST) has been hampered by low spatial resolution causing partial-volume effects. The high-resolution research tomograph (HRRT) is a brain-dedi

The positron emission tomography (PET) radiotracer (11)C-(R)-PK11195 allows the in vivo imaging in humans of the translocator protein 18 kDa (TSPO), previously called peripheral benzodiazepine receptor (PBR), a marker of inflammation. Despite its wid

Catechol-O-methyl transferase (COMT) is a pivotal regulator of brain dopamine function with a region-specific role. COMT is important in dopamine elimination in the prefrontal cortex, whereas dopamine reuptake is the main mechanism for synaptic remov

The C957T (rs6277) single nucleotide polymorphism (SNP) of the human dopamine D2 receptor (DRD2) gene (DRD2) affects DRD2 mRNA stability and has been shown to predict striatal DRD2 availability (B(max)/K(D)) in vivo in man. Specifically, the C/C geno

To study the relationship between gray matter atrophy and amyloid deposition in Alzheimer disease (AD).Volumetric magnetic resonance (MR) and [11C]-PIB PET were acquired from 23 patients with AD and 17 healthy older persons. Standardized [11C]-PIB up

The aim of this longitudinal positron emission tomography (PET) study was to evaluate the interrelationship between brain metabolism and amyloid accumulation during the disease process from mild cognitive impairment (MCI) to Alzheimer's disease (AD).

PET studies with N-methyl-[(11)C]2-(4':-methylaminophenyl)-6-hydroxybenzothiazole ([(11)C]PIB) have revealed an increased tracer uptake in several brain regions in Alzheimer disease (AD).To employ voxel-based analysis method to identify brain regions
