A Nuclear Medicine Stress Test is a diagnostic test that measures blood flow to your heart. During the test, a small amount of radioactive tracer is injected into a vein. A special camera, called a gamma camera, detects the radiation released by the tracer to produce computer images of the heart. The test usually involves taking two sets of images of your heart—one while you’re at rest and another after you heart is stressed, either by exercise or medication. Combined with exercise, the test can help determine if there is adequate blood flow to the heart during activity versus at rest.
A Nuclear Medicine Stress Test is ordered to rule out coronary artery disease (blockage of the coronary arteries) or as a follow up to Cardiac Catheterization, Angioplasty, Stent, or Coronary Artery Bypass Graft. This test is also known as Myoview, Thallium, Adenosine, Lexiscan or Non-Walking Stress Test.
Nuclear stress tests are available at both our Shadyside and Jefferson Offices.
