B) CT scan
C) PET scan
D) MRI

Question

Quizplus · Accepted Answer

MRI stands for Magnetic Resonance Imaging, which uses powerful electromagnets to create detailed images of the brain and other body parts. EEG (A) stands for Electroencephalography, which measures electrical activity in the brain using electrodes attached to the scalp. CT scan (B) stands for Computed Tomography, which uses X-rays and computer technology to create images of the body. PET scan (C) stands for Positron Emission Tomography, which uses a small amount of radioactive material to produce images of the body's metabolic activity. While these techniques may be used to study the brain, only MRI relies on powerful electromagnets to create detailed images.
