The AmyVid test uses a short-lived F-18 isotope that emits fairly low energy gamma rays. Because of it's short half-life, it has to be manufactured on site just before injection. Once injected, it will decay to insignificant levels in about 10-12 hours. Having worked with this isotope in my nuclear career, they selected an isotope that will do the job required for the PET scan, but will also have minimal impact on the body from a radiation standpoint.

Radiation is all around us. Smokers, airline pilots, and people working in quarries will likely get more radiation exposure than a patient will get from the AmyVid test, due to naturally occurring radiation or cosmic rays.

With my background in nuclear power and effects of radiation exposure, I would have no problem undergoing the AmyVid test, any more than I'd have getting an x-ray for a broken bone or routine dental exam. I think most people will be deterred by the cost and limited availability of locations offering the test more than the small radiation exposure involved.

LymPro will be a much easier and less costly test when available in the commercial market.
