angiocardiography /an·gio·car·di·og·ra·phy/ (-kahr″de-og´rah-fe) radiography of the heart and great vessels after introduction of an opaque contrast medium into a blood vessel or a cardiac chamber.
angiocardiography
angiocardiography [an″je-o-kahr″de-og´rah-fe]
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.
an·gi·o·car·di·og·ra·phy ( n j - -kärd- g r -f)n. Examination of the heart and associated blood vessels using x-rays following the injection of a radiopaque substance. an gi·o·cardi·o·graphic (--grf k) adj. |
angiocardiography
[-kär′dē·og′rəfē]
Etymology: Gk, angeion + kardia, heart, graphein, to record
the process of producing a radiograph of the heart and its great vessels. A radiopaque contrast medium is injected directly into the heart by a catheter introduced through the antecubital or femoral veins. X-ray films are taken as the contrast medium passes through the heart and great vessels. Also called cardiac angiography. Compare angiography.
angiocardiography [an″je-o-kahr″de-og´rah-fe]
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.

radiography of the heart and great vessels after introduction of an opaque contrast medium into a blood vessel or one of the cardiac chambers.
