positron emission tomography scan

Pronunciation: (PAH-zih-tron ee-MIH-shun toh-MAH-gruh-fee skan)

A procedure in which a small amount of radioactive glucose (sugar) is injected into a vein, and a scanner is used to make detailed, computerized pictures of areas inside the body where the glucose is taken up. Because cancer cells often take up more glucose than normal cells, the pictures can be used to find cancer cells in the body. Also called PET scan.

Definition from: Cancer.gov

PET (positron emission tomography) scan. The patient lies on a table that slides through the PET machine. The head rest and white strap help the patient lie still. A small amount of radioactive glucose (sugar) is injected into the patient's vein, and a scanner makes a picture of where the glucose is being used in the body. Cancer cells show up brighter in the picture because they take up more glucose than normal cells do. Exploración con TEP (tomografía por emisión de positrones). El paciente se acuesta en una camilla que se desliza a través de una máquina de TEP. El soporte de cabeza y la faja ajustadora blanca ayudan al paciente a permanecer inmóvil. Se inyecta en una vena del paciente una cantidad pequeña de glucosa (azúcar) radionucleica. El explorador toma una imagen de los lugares del cuerpo que utilizan la glucosa. Las células cancerosas tienen un aspecto más brillante en la imagen porque absorben más glucosa que las células normales. Date last modified: 2013-03-14
