A CT (computed tomography) scan is a test that uses X-ray images and computer processing to produce detailed cross-sectional images of the brain. An angiogram uses a dye and X-rays to visualize the blood vessels in the brain, while radionuclide imaging uses a radioactive tracer to create images. An MRI (magnetic resonance imaging) scan uses strong magnetic fields and radio waves to produce detailed images of the brain. While all of these imaging tests can be used to examine the brain, CT scans are specifically designed to construct a picture of the brain using X-ray images.
