I just did a little research. In the US state of Oregon there are 20 PET scanners for a population of 3.9 million people. In the Canadian province of British Columbia there are 2 for a population of 4.6 million. In Canada's largest population province of Ontario with 13.6 million people there are 13 PET scanners and they are only available to those who meet criteria the government has decided on.
