Importance of Chemistry in Pet-Ct Studies

Jasmina I. Alexander S*, Luz Abrego, Melissa Ballesteros, Evenith Campos, Damaris De Leon and Domingo Fernandez

Positron Emission Tomography - PET is an imaging technique in which the patient is given a tracer called a radiopharmaceutical, which is the union of a drug or a physiological substance with known pharmacokinetics and pharmacodynamics with a radioactive positron emitting atom. It allows us to correctly evaluate and measure relevant bodily functions: • blood flow • the use of oxygen • the metabolism of sugar (glucose). The most used radiopharmaceutical for carrying out a PET-CT study is Fluordeoxyglucose, whose full name is 2 -fluoro-2-deoxy-Dglucose, but its short form FDG is usually used.
