equilibrium radionuclide angiocardiography  a form of radionuclide angiocardiography in which images are taken at specific phases of the cardiac cycle over a series of several hundred cycles, with image recording set, or gated, by the occurrence of specific electrocardiographic waveforms.

first pass radionuclide angiocardiography  a form of radionuclide angiocardiography in which a rapid sequence of images is taken immediately after administration of a bolus of radioactive material to record only the initial transit through the central circulation.

radionuclide angiocardiography  a form in which the contrast material is a radionuclide, usually a compound of technetium 99m.
