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 positron emission tomography (PET) scan is a type of imaging test. It uses a radioactive substance called a tracer to look for disease in the body. A PET scan shows how organs and tissues are working. This is different than magnetic resonance imaging (MRI) and computed tomography (CT), which show the structure of, and blood flow to and from organs.
