D)computed tomography (CT)

Question

Quizplus · Accepted Answer

The brain-imaging method that takes computer-controlled X-rays of the brain is called computed tomography (CT) scanning. Electroencephalography (EEG) uses electrodes placed on the scalp to measure electrical activity in the brain. Magnetic resonance imaging (MRI) uses a magnetic field and radio waves to create detailed images of the brain. Positron emission tomography (PET) involves injecting a radioactive substance into the body and measuring its uptake in different parts of the brain to show brain activity.
