Nuclear Cardiology is a specialized branch of cardiology that uses small amounts of radioactive materials to diagnose and assess heart conditions. This technique involves imaging the heart to evaluate blood flow, identify blockages, and assess the heart's overall function. The most common procedure in Nuclear Cardiology is the myocardial perfusion scan, which helps doctors determine how well blood is reaching the heart muscle. By providing detailed images, this method aids in diagnosing conditions like coronary artery disease and guides treatment decisions effectively.
