Ali is in the hospital about to undergo a brain-imaging process that involves taking many X rays from different angles aided by the use of a computer. What type of imaging technique is being used?
A) electroencephalography (EEG)
B) magnetic resonance imaging (MRI)
C) positron-emission tomography (PET)
D) computed tomography (CT)

Question

Quizplus · Accepted Answer

The imaging process described in the scenario involves taking X-rays from different angles aided by a computer, which is a characteristic of computed tomography (CT). EEG involves recording electrical activity in the brain, MRI uses a magnetic field and radio waves to create images, and PET involves injecting a radioactive tracer to image metabolic activity in the brain. None of these techniques are described in the scenario.
