Question

A brain-imaging method that takes computer-controlled X-rays of the brain is called ________.
A) electroencephalography (EEG)
B) magnetic resonance imaging (MRI) 
C) positron emission tomography (PET)
D) computed tomography (CT)

Quizplus · Accepted Answer

The brain-imaging method that takes computer-controlled X-rays of the brain is called computed tomography (CT). Electroencephalography (EEG) measures electrical activity of the brain, magnetic resonance imaging (MRI) uses magnetic fields and radio waves to create images of the brain, and positron emission tomography (PET) measures the metabolic activity of the brain.
