Explanation:
Detailed explanation-1: -Positron emission tomography (PET) allows quantitative measurement of glucose metabolism using 2-[18F]-fluorodeoxyglucose (FDG).
Detailed explanation-2: -Commonly used brain imaging techniques are: functional magnetic resonance imaging (fMRI) computerized tomography (CT) positron emission tomography (PET)
Detailed explanation-3: -A PET scan shows how the brain and its tissues are working. Other imaging tests, such as magnetic resonance imaging (MRI) and computed tomography (CT) scans only reveal the structure of the brain.
Detailed explanation-4: -Electroencephalography (EEG) First discovered about a century ago, EEG measures electrical activities of the brain from electrodes placed on the scalp.
