WebInternational workshop on bio-medical applications of micro-PET sept. de 2010. In this work we investigate PET imaging with 68Ga and 66Ga isotopes (T1/2 of 67.63 min and 9.4 hours respectively). 68Ga and 66Ga are suitable as PET isotopes due to their half-lives, low energy production thresholds and characteristics β end-point energy. WebTo was mainly because the think to atoms beings did up from minor sub-atomic particles (protons, neutrons and electrons) owned not been developed. Nevertheless, the basis of the modern periodic table was well established and equally used to predict the assets of undiscovered elements long before that concept of the atomic number was developed.
