• PET Scan

• EEG

• CT/CAT Scan

• PET Scan

Drake's doctor had him drink a substance that contained a small amount of radioactive substance. Drake's doctor wanted to examine the activity level in Drake's brain when he played complex video games as a part of a research project. What kind of scan did Drake have?

Peggie tripped on the Lacrosse field and injured her knee. Her doctor did an ______ scan to see if she had done any soft tissue damage.

• MRI

• CT Scan

Scan uses traditional x-ray tech to create 3-D image of hard structures in the body. Used to identify fractures or the presence of tumors...can also be used to track tumor growth.

• PET Scan

• CT Scan

Uses magnetic field to create 3-D image of soft tissue areas of the body. It does not show level of activity or function.

• CT Scan

• MRI

Uses magnetic field and takes several scans just a few seconds apart. This creates an image of where oxygen is flowing to in the brain. So you can determine which areas of the brain are being used to complete certain tasks.

• PET Scan

• fMRI

Used to diagnose seizure disorders and also used in sleep studies, an ________________ records the electrical activity that is flowing across our brain surface constantly.

• PET Scan

• EEG
