What is a cardiac lexa scan?

Answer 1

A cardiac Lexiscan (also known as a myocardial perfusion imaging study) is a non-invasive nuclear imaging test that evaluates blood flow to the heart muscle. It involves the administration of a pharmacological agent called Lexiscan (regadenoson) to induce stress on the heart, simulating the effects of exercise. This is typically followed by the injection of a radioactive tracer, which allows for imaging of the heart using a specialized camera. The scan helps identify areas of reduced blood flow, aiding in the diagnosis of coronary artery disease and other cardiac conditions.
