Doctors use cardiac PET scans to diagnose coronary artery disease (CAD) and damage due to a heart attack. The system detects pairs of gamma rays emitted indirectly by a positron-emitting radioisotope, which is introduced into the body on a metabolically active molecule. ... | PowerPoint PPT presentation | … The CT images are matched with the PET scans. Among the body imaging technologies used in medicine, the PET unit is characterized by its use of positron-emitting tracer substances. The MGH Martinos Center's Christin Sander provides an introduction to positron emission tomography in this Why & How talk from March 17, 2016. 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).

A positron emission tomography (PET) scan is an imaging test that uses a special dye with radioactive tracers. Positron emission tomography (PET) is a type of nuclear medicine procedure that measures metabolic activity of the cells of body tissues. Positron emission tomography (PET) is an imaging tool that is widely used to diagnose several conditions such as cancer, heart disease, and brain disease. This site uses Akismet to reduce spam. Positron Emission Tomography (PET) 2. Use of positron emission tomography (PET) or PET/ computed tomography (CT) in Hodgkin lymphoma (HL) continues to expand worldwide. Positron Emission Tomography (PET) is covered for specific indications a. 1. 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.
