PET scan cognitively unimpaired vs. Alzheimer's disease

Caption

This image shows average tau buildup in the brain using PI-2620. The tracer uptake in different regions is measured by a quantitative method called Standardized Uptake Value Ratio (SUVR), helping compare tau levels. Warm colors (yellow, orange, red) indicate higher SUVR and more tau, while cooler colors (green, blue) show lower SUVR and less tau.
