a test that produces an image based on the uptake of glucose by a cancer to determine if a tumor is cancerous and if the cancer has spread.
A computer-based imaging technique that provides a picture of the brain's activity rather than its structure. The technique detects levels of injected glucose labeled with a radioactive tracer.
a computer-based imaging technique that uses radioactive substances to examine body processes. For example, a PET scan of the heart provides information about the flow of blood through the coronary arteries to the heart.
a method of imaging the brain by recording activity, as measured by cerebral blood flow, in different parts.
PET scan. A computerized image of the metabolic activity of body tissues used to determine the presence of disease.
This is a scan that provides three-dimensional pictures that can show the chemical activity of the tissues being examined.
For this type of scan, a person is given a substance that reacts with tissues in the body to release protons (parts of an atom). Through measuring the different amounts of protons released by healthy and cancerous tissues, a computer creates a picture of the inside of the body. Also called PET scan.
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 used. Because cancer cells often use more glucose than normal cells, the pictures can be used to find cancer cells in the body.
a computer-based imaging technique that provides a picture of the brain's activity rather than its structure by measuring levels of injected glucose which are labeled with a radioactive tracer.
An imaging scan that measures the brain function.
An image that helps a physician visualize body function; a radioactive glucose is often injected into the patient being scanned; if the patient has a tumor, more glucose will appear in that location
An imaging scan that measures the activity or functional level of the brain by measuring its use of glucose.
