Radionuclide ventriculography

Radionuclide ventriculography, a type of cardiac ventriculography, is a form of nuclear imaging, where a gamma camera is used to create an image following injection of radioactive material, usually Technetium-99m (Tc) labeled red blood cells. In radionuclide ventriculography, the radionuclide has the property of circulating through the cardiac chambers, availing for studies of the pumping function of the heart. In contrast, in myocardial perfusion imaging, the radionuclide is taken up by the myocardial cells, making its presence correlating with myocardial perfusion or viability of the cells.
