Imaging technique which measures the cerebral concentration of positron-emitting isotopes which are incorporated into biologically active compounds. The concentration of the tracers is determined by detectors positioned outside the head, and tomographic images are constructed by a computer in a way similar to CT or MRI. PET scanning can be used to measure cerebral blood flow, oxygen uptake, or glucose utilization. The technology is available at a few large medical centers where it is used in both research and specialized clinical applications; however it is not utilized routinely in diagnosis.
Computer-generated picture of the living brain, created by analysis of radioactive particles from isotopes injected into the bloodstream.
An imaging study that helps to distinguish cancer from benign tissue and assesses the response of cancer to therapy. A patient is injected with a tiny amount of radioactive material that is combined with a sugar. The test works on the principle that tumors metabolize (use up) more sugar than normal tissue.
A technique for examining brain function by observing the degree of metabolic activity of different regions of the brain.
Positron emission tomography scan. An imaging technique that may be used to find cancer in the body, or to determine how active the cancer is.
A variation of a scan that is like an MRI scan but is done in 3D and in colour.
Positron Emission Tomography is a technique that is used to build up clear and detailed pictures of the body. The person is injected with a glucose solution containing a very small amount of radioactive material. The scanner can 'see' the radioactive substance, and this shows where healthy cells are using the glucose in the body. Damaged or cancerous cells show up as areas where the glucose is being ignored.
Positron Emission Tomography is a modern technique used to study the activity of the brain.
A positron emission tomography scan uses a small dose of a chemical called a radionuclide combined with a sugar, which is injected into the patient. The radionuclide emits positrons. The PET scanner detects the positron emissions given off by the radionuclide.

a special test that is done to see if there's activity on both sides of the brain
a test that creates an image of the body using an injection of a substance, such as glucose (sugar), in a low-dose, radioactive form to determine the metabolic activity in cells
a type of medical technology that show the relative activity of various parts of the brain
a very reliable noninvasive test, but only in the hands of an experienced investigator
a very useful test to discover if someone is suffering from early stage lung cancer and is often used to discover if the cancer has spread to the lymph nodes
a way to find cancer in the body
A special type of X-ray using a radioactive dye which shows areas of the brain that have a higher or lower metabolism than normal. It can sometimes be used when an MRI scan alone is inconclusive. This is a limited-use diagnostic tool.
A total body scan that uses a radioactive form of glucose to detect cancer.
An imaging technique that uses radioactive positrons (positively charged particles) to detect subtle changes in the body's metabolism and chemical activities.
is a test often used to detect cancer
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).
Positron emission tomography, a brain-imaging technique tha uses radioactive glucose to measure the amount of glucose used by various areas of the brain during specific tasks.
Positron Emission Tomography scanning is one of the latest forms of technology for cancer diagnostics rendering much clearer imaging than conventional X-rays.
Positron emission tomography – specialized way to look at the organs of the body according to how fast they use sugar; can be used to detect cancerous cells.
ositron mission omography. A scan that uses a labeled sugar molecule to detect evidence of cancer in the body.
Positron Emission Tomography. A scanning device which uses low-dose radioactive sugar to measure brain activity.
Positron Emission Tomography test used to verify misothelioma diagnosis.
"Positron Emitting Tomography"- Utilizes a positive electron. Remember your basic chemistry: an electron is negative, so a positive electron can only mean one thing: anti-matter. By injecting anti-matter into the human body, these positron interact with electrons and produce small matter-antimatter explosions in which gamma rays are emitted. These are picked up by the scanner and create full color images of the body. The only known modality that can differentiate between living and dead tissue, the PET scan is hugely expensive due to the need to have a small, in-office nuclear accelerator available to create the positrons. Their half-life is about 15 minutes. Other than the huge expense, this is really the best imaging modality going. Boston Spine Clinics has yet to refer a patient for this imaging, but it is available here in Massachusetts and we would refer if the need arose.
Stands for Positron Emission Tomography. A type of scan that uses a low dose radioactive tracer to find abnormalities in the body. PET scans are sometimes used to help diagnose cancer. There is more about PET scans in About Cancer Tests.
Positron Emission Tomography. Use of elemental isotopes produced by a cyclotron that decay, releasing positrons (positive electrons) which are then used to visualize metabolic function (usually of brain).
a scan that takes pictures of the body and shows whether there are unusually high amounts of nutrients being processed; an imaging test to find malignant tumor cells in the body by injecting glucose into the body using a rotating scanner to show where more glucose is being used (malignant tumor cells take up more sugar than normal cells)
A brain scan used in research to study various chemical activity levels in the brain.
ositron emission tomography. A diagnostic imaging technique that uses a sophisticated camera and computer to produce images of how a person's body is functioning. A PET scans shows the difference between healthy and abnormally functioning tissues.
A scanning device which uses low-dose radioactive sugar to measure brain activity. This is a limited-use diagnostic tool.
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.
PET scans may be used to identify areas in the body that are affected by cancer. This test evaluates metabolic activity in different parts of the body using a radioisotope.
An acronym for "positron emission tomography," an imaging technique used to monitor and produce pictures of metabolic or biochemical activity in the brain
