Syllabus statements: (c) describe the principles of positron It has proved particularly useful for studying brain and heart functions and certain biochemical processes involving these organs (e.g., glucose metabolism and oxygen uptake). Positron emission tomography (PET) is a nuclear medical imaging technique for quantitative measurement of physiologic parameters in vivo (an overview of principles and applications can be found in [1]), based on the detection of small amounts of posi-tron-emitter-labelled biologic molecules. Positron emission tomography (PET) is a nuclear medicine imaging technique which produces a three-dimensional image or map of functional processes in the body. Positron emission tomography (PET) is a modern non-invasive imaging technique for quantification of radioactivity in vivo.It involves the intravenous injection of a positron-emitting radiopharmaceutical, waiting to allow for systemic distribution, and then scanning for detection and quantification of patterns of radiopharmaceutical accumulation in the body. Positron emission tomography is becoming an integral part of the diagnostic armamentarium in staging primary HNSCC and for surveillance for recurrence and monitoring therapeutic response to chemotherapy and radiation. Most common targets of functional imaging are oxygen, glucose, lactate metabolisms, cellular growth, perfusion, neurotransmitter sys-tems, organs and tissues. Positron Emission Tomography (PET) is a method for measuring biochemical and physiological processes in vivo in a quantitative way by using radiopharmaceuticals labelled with positron emitting radionuclides such as 11 C, 13 N, 15 O and 18 F and by measuring the annihilation radiation using a coincidence technique. The MGH Martinos Center's Christin Sander provides an introduction to positron emission tomography in this Why & How talk from March 17, 2016. Positron emission tomography (PET) is the study and visu-alization of human physiology by electronic detection of short-lived positron-emitting radiopharmaceuticals. Positron emission tomography (PET) is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other physiological activities including blood flow, regional chemical composition, and absorption.Different tracers are used for various imaging purposes, depending on the target process within the body. The CT images are matched with the PET scans. Positron Emission Tomography - PET 3D vs. 2D PET The main advantage of the 3-D acquisition in PET is an improved sensitivity of ~5-7 times the 2-D sensitivity. Among the body imaging technologies used in medicine, the PET unit is characterized by its use of positron-emitting tracer substances. PET is actually a combination of nuclear medicine and biochemical analysis. PET is currently widely utilized for response assessment after completion of therapy and, to a lesser extent, for pretreatment staging and assessment of response during therapy (therapy monitoring). Doctors use cardiac PET scans to diagnose coronary artery disease (CAD) and damage due to a heart attack. Positron emission tomography with CT (PET/CT) scanning is increasingly being used in head and neck cancer to assess response after radical concomitant chemoradiotherapy. Positron emission tomography (PET), imaging technique used in diagnosis and biomedical research. It uses radioactive tracers (called radionuclides) to produce pictures of your heart.

Positron emission tomography, also called PET imaging or a PET scan, is a type of nuclear medicine imaging. The concept of emission and transmission tomography was introduced by David E. Kuhal and Roy Edwards in the late 1950s at the university of Pennsylvania.
