UAB Alzheimer's Disease Center Core Cohort - Tau Imaging Substudy

Purpose

The primary objective of this study is to measure the concentration and the regional brain distribution of pathologic tau deposition using the PET tracer AV-1451 in participants in the UAB-ADC cohort. The amount and distribution of AV-1451 in the brain will be correlated to demographic, clinical, genetic, and biospecimen data acquired through the separate ongoing UAB-ADC study. Assessment of interactions between race and vascular risk factors, brain tau levels measured with AV-1451-PET, and cognitive status will be the primary outcome of this imaging study. Individuals participating in this AV-1451-PET/MRI study will also be enrolled in an ongoing [C-11]PiB-PET/MRI study (IRB-300001005, IND-138128), and their amyloid, tau and cognitive statuses will be compared in terms of race and vascular risk factors.

[F-18]AV-1451-PET/MRI 		All participants in this study will undergo a tau-PET imaging using the tracer [F-18]AV-1451 with a simultaneous PET/MRI system. The [F-18]AV-1451 dosage is 740MBq (10 mCi) given intravenously, and the PET/MRI imaging will occur 75-105 min after tracer injection.
  • Drug: [F-18]AV-1451-PET
    All study participants will undergo brain imaging with [F-18]AV-1451-PET/MRI. [F-18]AV-1451 is a PET imaging agent used primarily to measure the amount of abnormal tau protein deposition the brain.
