Quizplus · Accepted Answer

The brain-imaging method that takes computer-controlled X-rays to reveal "slices" of the brain is called computed tomography (CT). Option A, electroencephalography (EEG) is a method that measures electrical activity in the brain using electrodes attached to the scalp. Option B, magnetic resonance imaging (MRI) uses a magnetic field and radio waves to produce images of the brain. Option C, positron emission tomography (PET) uses a radioactive tracer to measure activity in the brain.
