AP PSYCHOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -A PET scan is a type of nuclear medicine imaging. Nuclear medicine uses small and safe amounts of radioactive material, called radiotracers, given through an IV.

Detailed explanation-3: -PET scanning utilizes a radioisotope tracer that is an analog to glucose, called fluorodeoxyglucose (FDG). FDG accumulates within malignant cells because of their high rate of glucose metabolism.

Detailed explanation-4: -Positron emission tomography (PET) scans are used to produce detailed three-dimensional images of the inside of the body. The images can clearly show the part of the body being investigated, including any abnormal areas, and can highlight how well certain functions of the body are working.

Detailed explanation-5: -Positron emission tomography (PET) uses small amounts of radioactive materials called radiotracers or radiopharmaceuticals, a special camera and a computer to evaluate organ and tissue functions. By identifying changes at the cellular level, PET may detect the early onset of disease before other imaging tests can.
