Brief Summary:
The investigators will conduct a study of brain positron emission tomography (PET) using 11C-PIB for the imaging of brain amyloid in 250 participants in the Multiethnic study of atherosclerosis (MESA) at Columbia University Irving Medical Center in New York City. Participants will be imaged only once with Pittsburgh Compound B (PIB) PET.

Condition or disease Intervention/treatment
Cognitive Impairment Vascular Diseases Alzheimer Disease Atherosclerosis Drug: 11C-PIB

Detailed Description:
This is a single center PET study of 11C-PIB. Eligible participants are current participants in the MESA study in New York City, without contraindications to MRI or PET procedures. Those eligible will have one brain PET scan with 11C-PIB within 12 months of a brain MRI. Vital signs will be checked prior to injection of 11C-PIB, 10 minutes after the injection, and again at the completion of the PET scan. The primary outcome measure for amyloid will be whole brain 11C-PIB SUVR. The relation between exposure groups and amyloid in the brain will be analyzed using linear regression.

Group/Cohort Intervention/treatment
MESA study participants
Current participants in the MESA study in New York City, 60 years or older, fluent in English or Spanish, able to participate in the brain imaging study
Drug: 11C-PIB
Participants will be injected with an intravenous bolus of up to 5-15mCi (370 MBq) (+/-10%) of [11C]PiB (over 5-10 seconds).
Other Name: PIB

Primary Outcome Measures :
  1. Whole Brain 11C-PIB SUVR [ Time Frame: 40 to 90 minutes post injection ]
    Standardized uptake value ratio (SUVR) of 11C-PIB;The extent of Aβ deposition in the brain will be quantified by[11C]PiB uptake visualized by PET using standardized uptake volume ratio (SUVR) of 6 primary cortical areas (i.e., anterior cingulate, prefrontal cortex, lateral temporal cortex, posterior parietal cortex, precuneus cortex, and anteroventral striatum) relative to the uptake in the cerebellum

Biospecimen Retention:   Samples Without DNA
We will store plasma and serum.
