Myocardial Perfusion Imaging Test 

​Nuclear Heart Scans use a special Gamma camera to take pictures of tissues and the heart after a radioactive tracer is put into a vein in the arm and is absorbed by the tissues.   The tracer allows the camera to see the activity and function of the tissues and heart.

Cardiolite Treadmill Stress Test 

A treadmill stress test with Myocardial Perfusion Imaging or Cardiolite is an exercise stress test that can be done in conjunction with nuclear imaging to increase the sensitivity of the test. This test uses a short-lived radioactive material, which along with computer imaging will help highlight any severely diseased blood vessels that may be causing diminished blood flow to the heart.

Nuclear Lexiscan Stress Test 

Lexiscan is a prescription drug given through an IV line that increases blood flow through the arteries of the heart during a cardiac nuclear stress test.  Lexiscan is given to patients when they are unable to exercise adequately for a stress test.  The test is done in conjunction with nuclear imaging.

Radionuclide Ventriculography (NVG)

Radionuclide Ventriculography is a form of nuclear imaging where a gamma camera is used to create an image following injection of radioactive material. The radionuclide has the property of circulating through the heart allowing the camera to capture the pumping function.
