The Nuclear Cardiology Laboratory at Mayo Clinic includes staff trained in cardiovascular diseases and radiology. The staff in the Nuclear Cardiology Laboratory collaborates to perform and interpret each study. This team approach ensures the technical and interpretive quality of each person's study.
In a nuclear stress test, doctors take images of your heart just after you've exercised on a treadmill or bicycle, or after you've been given medications to stress your heart, and again while you're at rest. In some cases, pacing may be used with people who have a pacemaker device.
During a nuclear stress test, doctors insert a radioactive dye called a tracer into a vein, usually in your hand or arm. Several different tracers may be used. The dye travels through your blood vessels to your heart. Imaging scans detect the radioactive dye and use it to develop images of your heart muscle. The scans show how well the blood flow is to your heart and can detect if you've had a heart attack.
Scans that are often used include:
