There are two parts to the viability test. First, a scan is done to measure resting blood flow in the heart. A radioactive tracer (either rubidium-82 or ammonia-13) is injected into your bloodstream and is taken up by the heart. The PET camera detects radiation released by the tracer to produce the images.
