Health Tip Real Time Imaging of Dengue

Positron emission tomography (PET) is an imaging technique where small quantities of radioactive materials, known as radiotracers, a computer and a camera are used to examine a patient''s tissues and organs. The images are used to determine the cellular changes that occur in the body and can be used for early detection of cancerous conditions. Initially this technique, combined with fluorodeoxyglucose (FDG), a glucose metabolism probe, was used to identify solid tumors by using PET. However, the procedure is gradually being considered archaic with newer and better imaging techniques becoming available.
