The technician who is performing the radionuclide angiogram test will attach electrodes to your chest for electrocardiography (ECG, EKG), which will also take place during the scan. You will be asked to lie down on an exam table under a gamma camera. A small amount of your blood will be drawn and mixed with the radioactive tracer, which will then be injected back into your bloodstream.
 
If your radionuclide angiogram will be used to assess how well your heart functions when you are exercising, you may be asked to lie on an exam table that has pedals at the end. You will be asked to pedal with your feet while the images are being gathered. Or you may be asked to exercise on a treadmill or stationary bike.
