I. Computerized Axial Tomography (CAT/CT)• CT scanning adds many X-ray images with

the aid of a computer to generate cross-sectional views of a patient's anatomy.

• CT scans are performed to analyze the internal structures of various parts of the body to view traumatic injuries

• CAT Scans can be used to view injuries or abnormalities in the brain to determine how to treat people appropriately

II. Electroencephalogram (EEG)

• EEG’s use small flat metal disks (electrodes) attached to the head to monitor the electrical impulses within the brain

• Information is taken down in a series of wavy lines

• This test is often used to test for epilepsy or other brain disorders that are caused by misfiring of neurons within the brain

III. Magnetic Resonance Imaging (MRI)

• Uses a magnetic field and radio waves to create detailed images of the organs and tissues within your body.

• The magnetic field temporarily realigns hydrogen atoms in your body. Radio waves cause these aligned atoms to produce very faint signals, which are used to create cross-sectional MRI images — like slices in a loaf of bread

• An fMRI (functional MRI) is used to detect activity (or lack thereof) in various parts of the brain

• If a part of the brain is not functioning or not functioning well, then a person could have some disorders

IV. Positron Emission Tomography (PET)

• In a PET scan, radioactive dye is injected into the body

• This dye will collect in your organs including the brain

• The subject is placed into a tunnel-shaped scanning machine that takes pictures of the radioactive dye in the brain

• This creates a 3D image of the brain• This scan is primarily used in psychology to

find areas of the brain that are placated due to Alzheimer's or other ailments
