Stress Nuclear Perfusion Imaging

The stress nuclear perfustion imaging procedure, also called a nuclear stress test, measures the extent of blood flow to the heart (i.e., myocardial perfusion).

Our physicians use this in conjunction with a patient's stress test, and it can be conducted on a stationary bicycle, a tread-mill, or by means of infusion of intravenous drugs to accelerate the heart rate. After the patient receives a small dose of radioactive tracer (thallium or technetium), physicians use a gamma camera to visualize the distribution of blood in the myocardium.
