Nuclear Medicine - Cardiac Nuclear Medicine
Cardiac nuclear medicine studies provide pictures of the structure and function of the heart.
Physicians use cardiac nuclear medicine studies to help diagnose cardiac disease. The symptoms include:
• unexplained chest pain
• chest pain brought on by exercise (called angina)
Cardiac nuclear medicine imaging is also performed:
• to visualize blood flow patterns to the heart walls, called a myocardial perfusion scan
• to evaluate the presence and extent of suspected or known coronary artery disease
• to determine the extent of injury to the heart following a heart attack, or myocardial infarction
• to evaluate the results of bypass surgery or other revascularization procedures designed to restore blood supply to the heart
• in conjunction with an electrocardiogram (ECG), to evaluate heart-wall movement and overall heart function with a technique called cardiac gating.
