There are two scanners used in nuclear medicine: the gamma camera, which uses technetium, and the PET scanner, which uses PET-ready pharmaceuticals. The gamma camera, depending on what you get, will cost something between $350,000 to $700,000 or $800,000. A PET scanner will cost something between $2 million and $3 million. The images you get from a PET scanner are a little different from those you get from a gamma camera. They do function in the same diagnostic manner; they give you the same broad information. PET scanners do require an infrastructure around them. They need cyclotrons within a geographic area. As I said, the Edmonton cyclotron is actually supplying two provinces directly and one province indirectly.
