Nuclear Imaging

Show Summary Details

Preview

Nuclear imaging techniques are commonly used to evaluate myocardial perfusion at rest and with stress, to measure left ventricular function and volume, and to determine the presence or absence of myocardial viability. Nuclear cardiology is based on the administration of a radiopharmaceutical consisting of a radionuclide (isotope) with or without a complexing agent (depending on the type of study) in order to image the cardiovascular system. Nuclear imaging is primarily used for measuring left ventricular volume and ejection fraction; assessing myocardial perfusion; assessing left ventricular size, function, and wall motion; and detecting right-to-left shunts. Limitations are also reviewed.
