a radiographic diagnostic study of the heart in which valves and vessels are examined via x-ray and fluoroscopy following the introduction of contrast media. See cardiac catheterization.
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. The data can be used to determine average activity during specific cardiac cycles or can be accumulated and displayed in rapid sequence, as a movie. Called also MUGA or multiple gated acquisition scanning and gated cardiac blood pool imaging.
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 radionuclide, recording only the initial transit of the isotope through the central circulation.
gated equilibrium radionuclide angiocardiography equilibrium radionuclide angiocardiography.
radionuclide angiocardiography a form in which the contrast medium is radioactively labeled, usually with technetium Tc 99m.
the display, by means of a stationary scintillation camera device, of the passage of a bolus of a rapidly injected radiopharmaceutical through the heart.
