Well, it's very difficult to quantify across the country. What I can tell you is we are very proud that we have the Ottawa Heart Institute as a flagship. As a flagship program, typically you have pretty much everything at your disposal to take care of your specific area.
Most nuclear medicine centres across the country, basically, are providing not only cardiac services but also oncology services. The way you handle thallium, for example, is different from the way you handle technetium, so management is not as easy as with the technetium.
Yes, we have seen some delays in the procedures because we cannot accommodate as many thallium patients as we can accommodate technetium patients, particularly also because most centres do not have access to PET scans to do cardiac studies. I don't know what the experience in Quebec is.
