Nuclear Cardiology

Nuclear cardiology studies are performed as a combined activity of the Penn State Heart and Vascular Institute and the Nuclear Medicine Division of the Department of Radiology. All aspects of cardiovascular scintigraphic imaging are offered for both adult and pediatric patients. State of the art digital gamma cameras are used for all procedures, permitting quantification of physiologic parameters when clinically indicated. Perfusion imaging, utilizing either thallium or sestamibi (Cardiolite), is performed in conjunction with either treadmill exercise or pharmacologic stress, utilizing Dipyridamole, Adenosine or Dobutamine. Right and left radionuclide ventriculograms (MUGA scans) provide a quantitative assessment of ventricular function as well as qualitative assessment of wall motion. Radionuclide shunt studies offer a non-invasive diagnosis for intracardiac shunting.

The Nuclear Cardiology Laboratory operates from 7:30 a.m. to 5:30 p.m. daily, Monday through Friday, and performs over 2,000 cardiac studies annually. Requests for emergency services are supported on a 24 hour per day basis, as clinically indicated. The staff includes a licensed nuclear cardiologist, two nuclear medicine physicians certified by the American Board of Nuclear Medicine, and an experienced technical staff, all certified by either the Nuclear Medicine Technology Certification Board or the American Registry of Radiologic Technologists, or both. A full time nurse certified in ACLS and PALS completes the staff.

The clinical service meets and exceeds guidelines on clinical imaging established by the American College of Radiology and the Society of Nuclear Medicine. The team includes:
