I recently had a cardiolite stress test. Almost all of the material I have read, do the stress test/treadmill then rest, then scan. When I had my test I was given cardiolite then rested then was scanned. After a short while I was given the treadmill test and was injected with more cardiolite. Then rested for a relatively short period then scanned again.
Why the difference in procedure and does it make any difference?
