Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

The technique in which radioactively tagged chemicals are introduced into the brain and then equipment monitors where the chemicals appear in the brain is what?

A	computerized tomography
B	magnetic resonace imaging
C	electrographic tomography
D	positron emission tomography

Explanation:

Detailed explanation-1: -A brain positron emission tomography (PET) scan is an imaging test of the brain. It uses a radioactive substance called a tracer to look for disease or injury in the brain. A PET scan shows how the brain and its tissues are working.

Detailed explanation-2: -Positron Emission Tomography (PET)

Detailed explanation-3: -Positron emission tomography (PET) is a functional imaging approach used to study the metabolism and physiology of the brain. PET studies have found that both acute and chronic alcohol ingestion alter blood flow and metabolism in various brain regions, including the frontal lobes and cerebellum.

Detailed explanation-4: -PET scans use injected radioactive material to help visualize active areas of the brain. A PET scan can be used to find malignant tumor cells or diagnose conditions like epilepsy. A small amount of radioactive glucose (a sugar) is injected into a vein.

Detailed explanation-5: -A positron emission tomography (PET) scan is an imaging test that can help reveal the metabolic or biochemical function of your tissues and organs. The PET scan uses a radioactive drug (tracer) to show both normal and abnormal metabolic activity.
