What is a PET scan?

NewYork-Presbyterian Hospital answered:Positron emission tomography is a type of nuclear imaging that can evaluate heart function. PET scans can be used to look for coronary artery disease by examining how blood flows through the heart; it can evaluate damage to heart tissue after a heart attack. Your physician can use this information to determine the best course of treatment for you.

American Heart Association answered:A cardiac PET (for “positron emission tomography”) scan is a non-invasive imaging technique that uses cross-sectional (tomographic) images and radioactive tracers to study and quantify how the heart tissue works. Cardiac PET scans are used to diagnose coronary artery disease (CAD) and can be used to identify injured but living heart muscle.

Positron emission tomography (PET) scanning is a type of imaging test that aids doctors in determining how glucose tissues and organs are using. Cancer and other metabolically active tissues such as the heart and brain utilize higher amounts of glucose.

Riverside Cancer Care Center answered:Unlike CT and MRI scans that provide images of structures in the body, PET scans show chemical changes related to metabolism or body activity. Before a PET scan, a patient will receive an injection of a small amount of a radioactive drug. All tissues absorb some of this drug -- called an isotope -- but cancerous cells are hypermetabolic, meaning they absorb greater amounts, which enables them to be seen on the scan. PET is used to locate cancerous tumors and to see if the disease has spread to other parts of the body.
Research indicates that combining the PET images into the images provided through CT scanning provides the best of both technologies. This procedure is particularly effective for diagnosing the original cancer site as well as any spread to nearby lymph nodes or more distant sites in the body.

Dr. Vijay Nuthakki of Aurora Health Care answered:PET stands for positron emission tomography. A patient is injected with a radio tracer commonly attached to a glucose molecule and this will be taken up by active sites in the body such as the brain and heart. The glucose is also taken by sites of cancer, infection, or inflammation. Most commonly the images are "fused" with CT scan images to specify anatomic sites of activity. Therefore, the PET scan provides "functional anatomy."

Dr. Ajay Sahajpal of Aurora Health Care answered:A PET scan is a positron emission test and is a nuclear medicine study typically used to locate or identify cancers. It occurs by using radio labeled sugar (FDG or flurodeoxyglucose, a glucose analog), which ideally go to actively dividing tissues or metabilically active tissues, such as tumors. Infections can mimic this and "light" up on a PET scan.
A PET scan can be "fused" with a CT or MRI to better enhance images and overlap with those to provide tumor localization.

Healthwise answered:Positron emission tomography (PET) is a test that uses a special type of camera and a tracer (radioactive chemical) to look at organs in the body.
During a PET scan, a radioactive substance called a tracer is typically injected into a vein (usually in the arm), but sometimes it may be inhaled. The tracer usually is a special form of a substance (such as glucose) that can be used (metabolized) by cells in the body.
A PET scan is often used to evaluate cancer, such as of the lung or colon. It also can be used to evaluate the heart's metabolism and blood flow and examine brain function.
PET scan pictures do not show as much detail as computed tomography (CT) scans or magnetic resonance imaging (MRI).

UCLA Health answered:PET scans are tests used to diagnosis tumors that are cancerous, such as some ependymomas. In this test, sugar that contains a safe level of radioactive material is injected into a vein of the person being tested. Sugar is used for energy by all cells of the body, and very active cells (such as cancer cells) use more sugar than other cells. Because of this, the radioactive sugar injected into the person builds up around cancer cells. The PET scanner is then used to take pictures of the inside of the body that show if areas with high sugar levels exist, thereby suggesting cancerous cells.
