A brain-imaging study can help your doctor zero in on more likely causes for your symptoms and rule out other causes. Brain-imaging procedures your doctor may recommend to help diagnose vascular dementia include: Computerized tomography (CT) scan. For a CT scan, you'll lie on a narrow table that slides into a small chamber.
A brain positron emission tomography (PET) scan is an imaging test of the brain. It uses a radioactive substance called a tracer to look for disease or injury in the brain. A PET scan shows how the brain and its tissues are working. Other imaging tests, such as magnetic resonance imaging (MRI) and computed tomography (CT) scans only reveal the structure of the brain. A PET scan requires a small amount of radioactive material (tracer).
