MRI (Magnetic Resonance Imaging) CORRECT ANSWER -Uses a magnetic field and
radio waves to create detailed images of the organs and tissues within your body
-Cross sectional MRI images are used, but it can also be used to produce 3-D images
PET (Positron Emission Tomography) CORRECT ANSWER -Uses a radioactive drug
(aka tracer) to show the functional activity of tissues and organs
-PET is commonly used in seizure patients to localize the part of the brain that is
causing the seizure activity
-The test evaluates glucose metabolism in the brain using the tracer (usually FDG)
CT (Computerized Tomography) CORRECT ANSWER -Combines series of x-ray
images taken from different angles and then creates cross-sectional images that look at
bones, blood vessels and soft tissues.
-Faster than an MRI
Angiogram CORRECT ANSWER -Minimally invasive test that uses x-rays and contrasts
to visualize vessels in the brain
-Can show aneurysm, AVM, blood clot, stroke
-Used with Wada test
Wada CORRECT ANSWER -Also known as an intracarotid sodium amobarbital study
-Looks at language and memory on one side of the brain at a time so that if the side that
controls language or has better memory, the surgeon may consider further testing prior
to epilepsy surgery
SPECT (Single Photon Emission Computerized Tomography) CORRECT ANSWER -A
radioactive substance (tracer) to evaluate blood flow in the brain
-An “ictal” SPECT can be done right after a seizure to localize seizure activity
