Comparison of Imaging Characteristics of 124I PET for Determination of Optimal Energy Window on the Siemens Inveon PET

BioMed Research International, Volume 2016, Issue 1, 2016., 2016
Purpose.124I has a half‐life of 4.2 days, which makes it suitable for imaging over several days over its uptake and washout phases. However, it has a low positron branching ratio (23%), because of prompt gamma coincidence due to high‐energy γ‐photons (602 to 1,691 keV), which are emitted in cascade with positrons. Methods.

Influence of the Generator in‐Growth Time on the Final Radiochemical Purity and Stability of  99mTc Radiopharmaceuticals

Science and Technology of Nuclear Installations, Volume 2013, Issue 1, 2013., 2013
At Legnaro laboratories of the Italian National Institute for Nuclear Physics (INFN), a feasibility study has started since 2011 related to accelerated‐based direct production of 99mTc by the 100Mo(p,2n) 99mTc reaction. Both theoretical investigations and some recent preliminary irradiation tests on 100Mo‐enriched samples have pointed out that both the
