Differential regional decline in dopamine receptor availability across adulthood: Linear and nonlinear effects of age
Human Brain Mapping, 4.
author keywords: aging; D2 receptors; dopamine; positron emission tomography imaging; regional differences
MeSH headings : Adult; Aged; Aged, 80 and over; Aging / metabolism; Brain / metabolism; Cross-Sectional Studies; Female; Humans; Magnetic Resonance Imaging; Male; Middle Aged; Models, Statistical; Positron-Emission Tomography; Receptors, Dopamine D2 / metabolism; Receptors, Dopamine D3 / metabolism; Young Adult

Individual Differences in Dopamine Are Associated with Reward Discounting in Clinical Groups But Not in Healthy Adults
The Journal of Neuroscience, 39(2), 321–332.
author keywords: decision making; delay discounting; dopamine; effort; PET; probability
MeSH headings : Adolescent; Adult; Aged; Aged, 80 and over; Aging / psychology; Behavior, Addictive / diagnostic imaging; Behavior, Addictive / psychology; Brain / diagnostic imaging; Brain / physiology; Brain Mapping; Delay Discounting; Dopamine / metabolism; Female; Humans; Individuality; Male; Mental Disorders / diagnostic imaging; Mental Disorders / psychology; Middle Aged; Positron-Emission Tomography; Receptors, Dopamine D2 / genetics; Receptors, Dopamine D2 / metabolism; Reward; Young Adult

Reproducibility of the correlative triad among aging, dopamine receptor availability, and cognition
Juarez, E. J., Castrellon, J. J., Green, M. A., Crawford, J. L., Seaman, K. L., Smith, C. T., … Samanez-Larkin, G. R. (2018, December 13). (Vol. 12). Vol. 12.
TL;DR:
Examination of correlations among adult age, dopamine D2-like receptor (D2R) availability, and cognition in two cross-sectional studies of healthy human adults found no consistent evidence for significant associations between low D2R availability and low cognitive performance on these measures, and suggest caution in using PET measures as evidence of broad age-related declines in fluid cognition.

Partial-volume correction increases estimated dopamine D2-like receptor binding potential and reduces adult age differences
Journal of Cerebral Blood Flow & Metabolism, 39(5), 822–833.

MeSH headings : Adult; Aged; Aging; Brain / physiology; Dopamine / metabolism; Female; Gray Matter / physiology; Humans; Male; Middle Aged; Positron-Emission Tomography / methods; Protein Binding; Receptors, Dopamine D2 / metabolism
TL;DR:
It is suggested that PVC increases estimated BPND in general and reduces adult age differences especially when using lower resolution cameras, and the past 30 years of research on dopamine receptor availability, for which very few studies use PVC, may overestimate effects of aging on dopamine receptors availability.
