Positron emission tomography Positron emission tomography. Positron emission tomography (PET) is a nuclear medicine functional imaging technique that is used to observe metabolic processes in the body. The system detects pairs of gamma rays emitted indirectly by a positron-emitting radionuclide (tracer), which is introduced into the body on a biologically active molecule.

Positron Emission Tomography Scan WHAT YOU SHOULD KNOW: A positron emission tomography scan is also called a PET scan. You may have a PET scan to take pictures of many body areas including the head, brain, neck, chest and abdomen. Before a PET scan, a small amount of radiation, called tracer, is put into your body. The tracer shows how chemicals, such as glucose, are working in your tissues.

Why Have a PET/CT Scan? PET/CT brings a number of benefits to cancer assessment and care. These include: Early detection and intervention. A PET/CT scan may reveal metabolic changes in the body prior to changes in structure that normally would show up on conventional medical imaging studies, such as MRI, CT, or x-ray. PET/CT can show whether tumor is benign or malignant.

PET (positron emission tomography) scan What does a PET scan show? PET scanning allows doctors to measure a range of activity including blood flow, blood volume, oxygen usage, tissue pH (acidity), glucose (sugar) metabolism, and drug activity. PET is very useful in watching the activity of cancerous tumors.

What Is a PET Scan? Why a PET Scan Is Performed. Your doctor may order a PET scan to inspect the blood flow, oxygen intake, and metabolism of your organs and tissues. PET scans are most commonly used to detect cancer, heart problems, brain disorders, and problems with the central nervous system.(Cleveland Clinic).he PET scan is able to measure blood flow, oxygen use, glucose metabolism (how your body uses sugar), and much more. A PET scan is typically an outpatient procedure, meaning that you will be able to go about your day after the test is complete.

Frequently Asked Questions CT and MRI scans are anatomic imaging modalities, which means that they look at the size and shape of organs and body structures. A PET scan is a metabolic imaging modality, which means it looks at cellular activity. The information collected from a PET scan is different from any other test that is available.

Pet Scan - FDG, Information, Cost PET images are different than those from more conventional radiological studies such as CT scan, Ultrasound, or MRI. PET scans are based on the metabolic activity and function of the organs. The images contain information on the function of a tissue rather than a static image like any x ray.

Positron Emission Tomography and Computed Tomography (PET-CT) Scans Positron Emission Tomography and Computed Tomography (PET-CT) Scans. A PET scan may be combined with a CT scan at many cancer treatment centers. However, you may hear your doctor refer to this procedure just as a PET scan. A PET-CT scan is one way to find cancer and learn its stage. Stage is a way to describe where the cancer is, if it has spread, and if it is changing how your organs work.

- Positron Emission Tomography (PET Scan). A positron emission tomography (PET) scan is a unique type of imaging test that helps doctors see how the organs and tissues inside your body are actually functioning.The test involves injecting a very small dose of a radioactive chemical, called a radiotracer, into the vein of your arm.ne of the main differences between PET scans and other imaging tests like CT scan or magnetic resonance imaging (MRI) is that the PET scan reveals the cellular level metabolic changes occurring in an organ or tissue.

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 scan. Introduction. Positron emission tomography (PET) scans are used to produce detailed three-dimensional images of the inside of the body. The images can clearly show the part of the body being investigated, including any abnormal areas, and can highlight how well certain functions of the body are working. PET scans are often combined with computerised tomography (CT) scans to produce even more detailed images.

Positron Emission Tomography (PET Scan) What are the reasons for a PET scan? In general, PET scans may be used to evaluate organs and/or tissues for the presence of disease or other conditions. PET may also be used to evaluate the function of organs such as the heart or brain. Another use of PET scans is in the evaluation of the treatment of cancer.
