Your physician has scheduled a special examination of your heart. This test is performed after an intravenous catheter is placed. This is used for injection(s) of radioactive tracer that allows a scanner to take images of the heart. This procedure also includes a stress test either performed on a treadmill or if you are unable to walk, a medication will be used which will obtain similar results to that achieved by a treadmill stress. The radioactive tracers are not dyes containing Iodine, they are short-lived isotopes, which decay rapidly and also excrete from the body through the urine and feces.

Arrival Time: Please arrive 15 minutes prior to your appointment.

**Approximate time for test is 1-2 hours.**
