Positron Emission Tomography (PET) A PET scan is a very accurate way to diagnose coronary artery disease and detect areas of low blood flow in the heart. PET can also identify dead tissue and injured tissue that’s still living and functioning. If the tissue is viable, you may benefit from a PCI or coronary artery bypass surgery.

PET Scan PET scanning is most commonly used in the diagnosis and assessment of cancer. However, it can be used to diagnose other conditions including Alzheimer's disease, epilepsy and heart disease. In cancer medicine, doctors may use the scan for the following reasons: 1  To detect a cancer. 2  To ' stage ' or show how advanced a cancer is. 3  To see whether a cancer has spread to other parts of the body. 4  In decisions about the best treatment for a cancer. 5  To see how well treatment with cancer medication is working. 6  To show the difference between ...

- Test Overview. 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. The tracer usually is a special form of a substance (such as glucose) that collects in cells that are using a lot of energy, such as cancer cells.

Overview The tracer may be injected, swallowed or inhaled, depending on which organ or tissue is being studied by the PET scan. The tracer collects in areas of your body that have higher levels of chemical activity, which often correspond to areas of disease. On a PET scan, these areas show up as bright spots. A PET scan is useful in revealing or evaluating several conditions, including some cancers, heart disease and brain disorders.

What is a PET Scan and How Does it Work? In patients with memory disorders, doctors use PET scans of the brain to look for brain tumors that can be surgically removed. Here's how it works. A nurse injects a patient with a radioactive substance that attaches to a compound in the body such as sugar, called glucose.

Positron Emission Tomography (PET) A PET scan of the heart is a noninvasive nuclear imaging test. It uses radioactive tracers (called radionuclides) to produce pictures of your heart. Doctors use cardiac PET scans to diagnose coronary artery disease (CAD) and damage due to a heart attack. PET scans can show healthy and damaged heart muscle.

Principles of positron emission tomography imaging N2 - Positron emission tomography (PET) is a noninvasive medical imaging technology that can generate high-resolution images of human and animal physiological functions. It is used for a variety of clinical applications in oncology, neurology, and cardiology, but the principal clinical application of PET is in oncology, where it is used to locate malignant tumors.

Lung PET Scan Positron emission tomography (PET) is a sophisticated medical imaging technique. It uses a radioactive tracer to pinpoint differences in tissues on the molecular level. A PET scan can detect differences in body functions, such as blood flow, use of oxygen, and uptake of sugar (glucose) molecules. This allows your doctor to see how certain organs are functioning. A lung PET scan is often combined with a lung CT scan to detect conditions like lung cancer.

Mesothelioma Imaging Scans Patients are injected with a radioactive tracer isotope combined with some form of glucose. After a short time, the scanners are able to detect gamma radiation produced by the tissues in the body that are interacting with the tracer isotope. PET scans create detailed images of the body. They can even detect changes in biological processes, allowing doctors to find the smallest tumors.
