PET Scan PET stands for positron emission tomography. A PET scan produces three-dimensional, colour images of your body using radionuclides (for more information on radionuclides see separate leaflet called Radionuclide Scan). PET scans show where cells are particularly active. PET can be used to diagnose various medical conditions, or to find out more about how a condition is developing. It can also be used to measure how well treatment for a condition is working.

- 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.

- Shades of blue and black indicate decreased or no activity within a brain region. In essence, a PET scan produces a “map” of the active brain. Scientists can use PET scans to see what happens in the brain when a person is engaged in a physical or mental activity, at rest, or even while sleeping or dreaming. Certain tracers can track the activity of brain chemicals, for example neurotransmitters such as dopamine and serotonin.

What sorts of diseases can a PET scan detect, other than cancers? A PET scan can measure such vital functions as blood flow, oxygen use, and glucose metabolism, which helps doctors identify abnormal from normal functioning organs and tissues. The scan can also be used to evaluate the effectiveness of a patient’s treatment plan, allowing the course of care to be adjusted if necessary.

PET (positron emission tomography) scan How does a PET scan work? A PET scan integrates two technologies to view your body: computed tomography (CT) and a radioactive material called a tracer. The tracer is what allows doctors to see how your body tissues absorb and use different chemicals in real time.

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.

What Is a PET Scan? The 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.

Heart PET Scan What Is a Heart PET Scan? A positron emission tomography (PET) scan of the heart is an imaging test that uses specialized dye to allow your doctor to view problems with your heart. The dye contains radioactive tracers, which concentrate on areas of the heart that may be injured or diseased.

Overview The pictures from a PET scan provide information different from that uncovered by other types of scans, such as computerized tomography (CT) or magnetic resonance imaging (MRI). A PET scan or a combined CT-PET scan enables your doctor to better diagnose your condition.

- PET stands for positron emission tomography, and this generally uses a safe radioactive tracer molecule called 18F-fluoro-2-deoxy-D-glucose (FDG). Fortunately, that’s not on the quiz — you don’t need to know it. All that is worth knowing is that PET scans offer “metabolic imaging”, which detects differences in the metabolism of tissues.

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 ...

PET/CT Scan: How to Prepare, What to Expect & Safety Tips You are here. Prepare for a PET/CT scan. Positron emission tomography, also called PET imaging or a PET scan, is a diagnostic examination that involves getting images of the body based on the detection of radiation from the emission of positrons. Positrons are tiny particles emitted from a radioactive substance administered to the patient.

PET scan A PET scan can show how body tissues are working, as well as what they look like. It can help to diagnose and stage a cancer. This helps your doctor decide which treatment you need and whether your treatment is working. A PET scan can also sometimes tell if an area in the body is scar tissue or an active cancer.

- PET stands for “positron emission tomography”, and a PET scan is a procedure designed to identify abnormal cellular activity that might indicate cancer. A prominent use for the PET scan (or combination PET/CT) is in achieving accurate staging of cancer.

Positron Emission Tomography (PET) A PET scan can help in determining if you’ll benefit from a cardiac procedure (PCI) or surgery to restore blood flow. The tracers used for PET scans can help identify injured but still living (viable) heart muscle that might be saved if blood flow is restored. Why do people have cardiac PET scans? 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. How does a PET scan work?

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 scan for breast cancer Breast PET scan. A breast positron emission tomography (PET) scan is an imaging test that uses a radioactive substance (called a tracer) to look for breast cancer. This tracer can help identify areas of cancer that an MRI or CT scan may miss. A PET scan requires a small amount of radioactive material (tracer). This tracer is given through a vein (IV), usually on the inside of your elbow. It travels through your blood and collects in organs and tissues. The tracer helps the radiologist see certain areas or diseases more clearly.

- What is PET? PET (or positron emission tomography) is a medical imaging tool which assists physicians in detecting disease. A PET scan produces digital pictures that can, in many cases, identify many of the most common forms of cancer, including lung, breast, colorectal, lymphoma and melanoma. Technically, PET is a medical imaging technology that images the biology of disorders at the molecular level before anatomical changes are visible.

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.

About This Procedure PET-CT overview. 1  PET (positron emission tomography) looks at how the cells in your body process a radioactive tracer material that you drink, inhale, or have injected. 2  CT (computed tomography) uses X-ray technology to produce detailed images. 3  By combining two scans, a PET-CT shows both your anatomy and how your cells are behaving.

Positron Emission Tomography and Computed Tomography (PET-CT) Scans Doctors combine these tests because a CT scan and PET scan show different things. A CT scan shows detailed pictures of tissues and organs inside the body. A PET scan shows abnormal activity. So, the 2 scans together provide more information about the cancer.
