AP PSYCHOLOGY

Detailed explanation-1: -CT scans and MRIs are both used to capture images within your body. The biggest difference is that MRIs (magnetic resonance imaging) use radio waves and CT (computed tomography) scans use X-rays.

Detailed explanation-2: -Magnetic resonance imaging (MRI) uses changes in electrically charged molecules in a magnetic field to form images of the brain. Both technologies are more precise than ordinary X-rays and can help find problems when people fall ill.

Detailed explanation-3: -There are three major types of brain scans. They are computed tomography (CT), magnetic resonance imaging (MRI), and positive emission tomography (PET).

Detailed explanation-4: -Magnetic resonance imaging (MRI) of the head uses a powerful magnetic field, radio waves and a computer to produce detailed pictures of the brain and other cranial structures that are clearer and more detailed than other imaging methods.
