Nuclear Stress Tests
Myocardial Perfusion Imaging (nuclear stress testing) utilizes radioactive tracers to obtain images of your heart. The tracer is injected through a small I.V. in your arm or hand. The radioactive tracer does not contain any iodine dye. Pictures of your heart are taken at rest and again after your treadmill stress test. The pictures will take approximately 15 minutes to complete. ACA's specialty trained cardiologist will interpret these images, along with the EKG tracings and other information recorded during your test to evaluate you for heart disease. If you are unable to exercise on a treadmill (as determined by your cardiologist) he or she may order a non-walking or pharmacologic stress test. Instead of walking on a treadmill you will be given a medication through your I.V. Our office offers Lexiscan Myocardial Perfusion Imaging and Dobutamine Myocardial Perfusion Imaging as alternatives. Your cardiologist will determine which medication is the appropriate alternative to exercise based on your personal medical history. All nuclear stress testing takes approximately 2 1/2 to 3 hours. Special preparation is necessary. If your cardiologist has ordered this test, please click the link below to view the preparation instructions and to print and fill out the medical history questionnaire. Please bring this questionnaire with you when you come in.
