- 1 PET is an acronym for positron emission tomography. 2  PET scans are often used to diagnose a condition or how a condition is developing.  They are used alongside X-rays or MRI (magnetic resonance imaging) scan to diagnose or provide more insight into a condition.

- A positron emission tomography (PET) scan is an imaging test that allows doctors to check for disease in your body. The scan uses radioactive tracers in a special dye. These tracers are injected into a vein in your arm and are then absorbed by your organs and tissues. positron emission tomography (PET) scan is an imaging test that allows doctors to check for disease in your body.

Tumor Quantification in Clinical Positron Emission Tomography Positron emission tomography (PET) is used extensively in clinical oncology for tumor detection, staging and therapy response assessment. Quantitative measurements of tumor uptake, usually in the form of standardized uptake values (SUVs), have enhanced or replaced qualitative interpretation. In this paper we review the current status of tumor quantification methods and their applications to clinical oncology.

PET/CT (Positron Emission Tomography) scans use radioactive materials to diagnose the presence of disease in the body. PET/CT’s advanced imaging capabilities can identify changes in organs and body function. PET/CT scans can help diagnose and stage are cancers of all types (lymphoma, breast, colon, skin, etc.).

About This Procedure A PET-CT exam combines two types of scans to help pinpoint abnormal activity in the body. A PET (positron emission tomography) scan creates an image of your body's metabolic activity and shows the rate at which your body's cells break down and use sugar (glucose).

PET/CT Scans What is a PET/CT Scan? A PET/CT scan is a powerful imaging technique that provides a more precise diagnosis for many diseases. Positron emission tomography (PET) is a nuclear medicine imaging procedure that looks at the metabolic activity in your body and can reveal changes in cellular function.

PET scan Positron emission tomography (PET) scan A computerized diagnostic technique that uses radioactive substances to examine structures of the body. When used to assess the brain, it produces a three-dimensional image that reflects the metabolic and chemical activity of the brain.

- Positron emission tomography: Unlike CT or MRI, which look at anatomy or body form, PET studies metabolic activity or body function. As a result, PET can detect tumors in lymph nodes, for example, even before they enlarge and are detectable with MRI or CT. In PET imaging, the patient receives a small intravenous injection of a radio-active medication (a form of sugar).

PET scan Why PET scans are used. An advantage of a PET scan is that it can show how well certain parts of your body are working, rather that showing what it looks like. They're particularly helpful for investigating confirmed cases of cancer, to determine how far the cancer has spread and how well it's responding to treatment.

Positron Emission Tomography (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.

Brain PET scan A brain positron emission tomography (PET) scan is an imaging test of the brain. It uses a radioactive substance called a tracer to look for disease or injury in the brain. A PET scan shows how the brain and its tissues are working. Other imaging tests, such as magnetic resonance imaging (MRI) and computed tomography (CT) scans only reveal the structure of the brain. A PET scan requires a small amount of radioactive material (tracer).

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. Knowing this helps you and your doctor choose the best treatment.

Cardiovascular Tests and Procedures A positron emission tomography (PET) scan is a type of imaging test. It uses a radioactive substance called a tracer to look for disease in the body. A PET scan shows how organs and tissues are working. This is different than magnetic resonance imaging (MRI) and computed tomography (CT), which show the structure of, and blood flow to and from organs. Many places have machines that combine the PET and CT images, so that only one exam is performed.

PET scan PET scan stands for Positron Emission Tomography, an imaging exam that is designed to help reveal the way that the tissues and the organs are functioning. This is a medical diagnostic exam that requires the use of a small amount of radioactive material in order for this activity to be apparent.

PET (positron emission tomography) scan A positron emission tomography (PET) scan is a type of nuclear imaging test that shows the metabolic activities (energy usage) of your brain. While X-ray, CT, and MRI scans look at the anatomy of your brain, a PET scan can give your doctor information about how your brain is working.

PET Scan PET stands for positron emission tomography. A PET scan produces three-dimensional, colour images of your body using radionuclides. See separate leaflet called Radionuclide (Isotope) Scan for more information on radionuclides. PET scans show where cells are particularly active.

- Advanced Search. 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 shows if your heart is getting enough blood or if blood flow is reduced because of narrowed arteries. It also shows dead cells (scars) from a prior heart attack. 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.

Hypertonic Definition and Examples If there is a higher concentration of solutes outside of the cell than inside it, such as would happen if you placed red blood cells in a concentrated salt solution, then the salt solution is hypertonic with respect to the inside of the cells.
