During a PET/CT scan for dementia, a special dye is injected into the body that helps to identify areas of the brain that are not functioning properly. These areas will show up as dark spots on the scan, indicating where there may be damage or deterioration in the brain.
PET/CT scans can also help doctors monitor the progression of dementia over time. By comparing scans taken at different times, doctors can see how the brain is changing and whether treatment is helping to slow the progression of the disease.
