Amyloid PET scan (IMAGE)
Caption
Amyloid PET imaging was used in the study to measure plaque buildup in the brain, a hallmark of Alzheimer's disease. Warmer colors indicate higher amyloid levels. Participants with healthier patterns of brain blood flow and oxygen regulation had lower amyloid burden, reinforcing the idea that vascular function may be linked to Alzheimer's-related changes.
