Positron-Emission Tomography


CSP: 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.,NCI: A procedure in which a small amount of radioactive glucose (sugar) is injected into a vein, and a scanner is used to make detailed, computerized pictures of areas inside the body where the glucose is used. Because cancer cells often use more glucose than normal cells, the pictures can be used to find cancer cells in the body.,NCI: An imaging technique that utilizes positron emission tomography and computed tomography in a single machine.,MSH: An imaging technique using compounds labelled with short-lived positron-emitting radionuclides (such as carbon-11, nitrogen-13, oxygen-15 and fluorine-18) to meas
