Well, the best alternative for what we call conventional nuclear medicine procedures, SPECT imaging with technetium or other single-photon tracers, is basically positron emission tomography. There is a good reason these tests exist and there's a good reason that we must promote their use and continue to use them.
I fully agree with Dr. Lyons, with whom I am working, that what we ought to do gives us and Canada and its medical community a chance to show leadership. We ought to use a socialized step approach to medicine by defining the very best test. Technology is evolving very fast. What was true yesterday might not be true tomorrow, so when you're talking about alternatives, our preference for nuclear medicine tests--single-photon tests and technetium--would be to use an alternative nuclear medicine procedure.
