Scanning the Human Body
EQ: What types of scans can we use to study the human body and what do they tell us?
An MRI Machine
Slide2I. 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

Slide4II. 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

WTH!!! I thought Mom said I was getting an Egg!!!
Slide6III. Magnetic Resonance Imaging (MRI)
Uses
a magnetic field and radio waves to create detailed images of the organs and tissues within your body
.
T
he
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
Slide7III. Magnetic Resonance Imaging (MRI)
Slide8IV. 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
