Brain and head MRI scans
A Magnetic Resonance Imaging (MRI) scan uses a combination of magnets and radio waves to accurately capture internal images of the body. An MRI scan requires no surgical incision and it can be done on any part of the body. Unlike X-ray or CT scans which only take pictures of your bones, an MRI scan allows you to see all the bones, cartilage, ligaments, tendons, muscles, and blood vessels of the body. Therefore, it is far better at finding and evaluating problems in the brain. Also, X-rays and CT scans have ionizing radiation while MRI is safe, with no harmful radiation. In general, CT of the brain is used to evaluate patients with recent trauma to exclude a skull fracture or bleed in the brain while MRI is used for almost all other reasons.
