Positron Emission Computed Tomography (PET/CT Scan)

The increasing acceptance of FDG¿PET in clinical oncology, led to the widespread use of this technique of examination. In parallel, important technological improvements such as the introduction of hybrid systems which couple PET with X ray computed tomography (PET/CT) using a radiolabelled pharmaceutical called 2-fluoro-2-deoxyglucose (18FDG) when given to a patient, his semipermeable cells membranes assumes it as glucose molecules to be used in metabolism and anabolism such as glucose cycle, citric acid cycle, Kerb's cycle, Cure cycle, urea cycle, etc... Carcinogenic cells and/or activated cells to study a certain function absorbs more 18FDG molecules than the normal or rest ones to appear more pronounced 3D images useful for accurate diagnosis for many medical and functional cases. Cyclotrons and accelerators, Safety and security purposes, theoretical calculation for radionuclide recovery on basis of nuclear chemistry, Radionuclide as well as 18FDG production have been extensively discussed in this book.
