Imaging Energy
Since the goal of radionuclide therapy is to destroy
cells, high energy particles are preferred. While there is no exact minimum
energy required, beta emitters with Emax >1 meV are
preferred. The LET of these high energy particles is sufficient to cause
adequate but regulated tissue damage. Some therapeutic isotopes, e.g.,
I-131, are imageable and add to the information obtained during therapeutic
treatment.
