I'd like to comment on your first question, about the experts.
What we'd like to see from any government is the government engaging medical associations, and not necessarily individuals. At times we find an individual from an expert panel we never heard of. That's the first thing.
In terms of PET scintigraphy, it is going to vary from province to province. We estimate that if we have PET scintigraphy available today in Canada we would be able to shift anywhere from 10% to 25% of the technetium study to PET.
