Stress test that: includes the use of an injectable material to help visualize areas of the heart while you are active. It is more sensitive than the standard stress test.

Stress test: A nuclear stress test detects blood supply to the heart. A radioactive tracer is injected into the veins at peak exercise or with a vasodilator. The tracer is taken up by the heart cells and the uprake is proportional to blood flow. By comparing uptake at rest versus exercise we can determine if blood flow is compromised.
