The first way of creating an image of the brain was the _ scan. _ is injected into the blood to increase _. _ are then passed through the head at one level and recorded by detectors on the opposite side. This is then repeated at the next level. A _ constructs images of the brain. A disadvantage of this is that the patient is exposed to _.

_ scanners measure the emission of radioactivity from injected _. When a radioactive atom decays, it releases a _ that immediately collides with a nearby _, emitting two _ rays in exactly opposite directions. The person's head is surrounded by detectors, and a computer uses their information to determine how much of the _ is in each area. However, this method provides low _ resolution and is _.

In an MRI scan, _ atoms align along the magnetic field. A _ pulse flips the atoms, and when they return to their original state they emit a signal that creates an image. Different tissues emit signals at different _. A disadvantage of this is that the person must lie as _ as possible.
