Violet 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 technique described in the scenario, which involves taking X-rays from different angles and using a computer to create images, is computed tomography (CT). Electroencephalography (EEG) measures brain electrical activity, magnetic resonance imaging (MRI) uses a magnetic field and radio waves to create images, and positron emission tomography (PET) uses a radioactive substance to create images of brain function. None of these techniques match the description given in the scenario.
