From our perspective, the technetium market will be flat at best, or will decrease to a certain percentage over 10 years, and the PET technology will increase significantly as soon as the equipment and the infrastructure are built. The PET technology offers a very nice alternative with better sensitivity and specificity, so it will give better results than what we have today.
It's like comparing what we had at the beginning when we were talking about thallium versus Cardiolite. Thallium was the first generation; Cardiolite, technetium, is the second generation. We believe that PET is the third generation. But considering the fact that there is a cost related to that, we still believe that technetium will play a role, but it will not increase in North America. It'll probably decrease slightly over the next 10 years.
