Summary

The radionuclide Tc-94m with its positron branching ratio of 72, positron end-point energy of 2.47MeV, and relatively short half-life of 52 minutes is suitable for quantitative measurements using PET. Tc-94m can be produced by proton bombardment of isotopically enriched [Mo-94]MoO₃. We prepare Tc-94m as pertechnetate in saline solution using a wet-chemical separation procedure employing a semi-automated apparatus. Tc-94m sestamibi and other radiopharmaceuticals are routinely produced from this reagent.
