종양환자의 진료에 있어서 양전자방출 단층촬영술(Positron Emission Tomography, PET)의 유용성에 대한 고찰
최재걸,송문갑 고려대학교 의과대학 1998 고려대 의대 잡지 Vol.35 No.2
Positron emission tomography(PET) is a diagnostic method that creates high resolution, 3 dimensional tomographic images of the distribution of positron emitting radionuclide in the human body. The radionuclide compounds used include substrates, ligands, drugs. antibodies, neurotransmitters and other biomolecules that are tracer for specific biological processes. Thus the resulting PET images can be considered images of these biochemical or physiological processes(functional images). Positron emission tomography is now primarily used in oncological indications owing to the successful application of fluoline-18 fluo-rodeoxyglucose(FDG) in increasing number of clinical indications at different stages of diagnosis, and for staging and follow-up. This review will discuss detailed clinical applications based on current achievements in respect of various organs and tumors.
