Radioisotopes production
Positron Emission Tomography scans used very short lived radioisotopes. These isotopes should be produced by a cyclotron at the hospital itsel or when the lifetime is enough long, delivered very quickly from a regional center (in the case of most used fluorine-18 the half-life is 110 minutes). The supply in technetium-99 for gamma cameras trequires a much a relatively simple device recharged twice a week : technetium-99 is needed in 70% of scintigraphies.
