Abstract

Positron emitting radionuclides have unique properties that make them nearly ideal as radioactive tracers for in vivo metabolic studies. Using positron emission tomographic (PET) scanning and positron-labeled radiopharmaceuticals, one can study local glucose metabolism in tissues, blood flow, oxygen utilization, protein synthesis, and many other functions noninvasively in normal subjects and patients who have various diseases. A review of some of these techniques and the relative advantages and problems associated with the PET approach is presented.
