Calorimetry, Differential Scanning definition: Differential thermal analysis in which the sample compartment of the apparatus is a differential calorimeter, allowing an exact measure of the heat of transition independent of the specific heat, thermal conductivity, and other variables of the sample.
positron emission tomography definition: detection of gamma rays emitted from tissues after administration of a natural substance such as glucose or fatty acids into which positron emitting isotopes have been incorporated; the paths of the gamma rays, which result from collisions of positrons and electrons, are interpreted by a computer algorithm, and the resultant tomogram represents local concentrations of the isotope containing substance.
proton magnetic resonance spectroscopic imaging definition: A computerized image of the metabolic activity of body tissues used to determine the presence of disease.
Positron-Emission Tomography definition: An imaging technique using compounds labelled with short-lived positron-emitting radionuclides (such as carbon-11, nitrogen-13, oxygen-15 and fluorine-18) to measure cell metabolism. It has been useful in study of soft tissues such as CANCER; CARDIOVASCULAR SYSTEM; and brain. SINGLE-PHOTON EMISSION-COMPUTED TOMOGRAPHY is closely related to positron emission tomography, but uses isotopes with longer half-lives and resolution is lower.
Positron Emission Tomography definition: A technique for measuring the gamma radiation produced by collisions of electrons and positrons (anti-electrons) within living tissue. In positron emission tomography (PET), a subject is given a dose of a positron-emitting radionuclide attached to a metabolically active substance (for example, 2-fluoro-2-deoxy-D-glucose (FDG), which is similar to a naturally occurring sugar, glucose, with the addition of a radioactive fluorine atom). When living tissue containing the positron emitter is bombarded by electrons, gamma radiation produced by collisions of electrons and positrons is detected by a scanner, revealing in fine detail the tissue location of the metabolically-active substance administered. (NCI04)
Positron emission tomography definition: Computed, Positron emission tomography
Radionuclide Imaging definition: The production of an image obtained by cameras that detect the radioactive emissions of an injected radionuclide as it has distributed differentially throughout tissues in the body. The image obtained from a moving detector is called a scan, while the image obtained from a stationary camera device is called a scintiphotograph.
Radionuclide Imaging definition: An imaging technique that uses a small dose of a radioactive chemical (isotope) called a tracer that can detect sites of cancer growth, trauma, infection or degenerative disorders. The tracer, which is either injected into a vein or swallowed, travels through the bloodstream to the target organ, and emits gamma rays, which are detected by a gamma camera and analyzed by a computer to form an image of the target organ.
radionuclide scanning definition: A test that produces pictures (scans) of internal parts of the body. The person is given an injection or swallows a small amount of radioactive material; a machine called a scanner then measures the radioactivity in certain organs.
Tomography, Emission-Computed definition: Tomography using radioactive emissions from injected RADIONUCLIDES and computer ALGORITHMS to reconstruct an image.
