Nuclear cardiac imaging uses special radionuclide dyes to check blood supply to the heart muscle and heart function. During these tests, the doctor injects a small amount of dye into the patient's vein. A camera then "picks up" the dye, looking for areas of the heart that are not receiving enough blood.
The University of Chicago Medicine was instrumental in developing the field of clinical nuclear medicine. Today, our doctors use the latest technologies to screen patients at high risk for coronary artery disease, but who may not have any symptoms. Using nuclear imaging, doctors also can determine if patients with existing heart disease may benefit from interventional treatment.
