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.

The angiocardiography and echocardiography of this patient showed that the left ventricular wall motion almost disappeared, the left ventricular end-diastolic pressure remarkably increased, and the ventricular function profoundly depressed.
This study was aimed to determine the diagnostic accuracy and impact of the systematic use of noninvasive tests such as, echocardiography and multidetector CT in preoperative paediatric patients with TOF and to determine the need for cardiac catheterization and invasive angiocardiography in patients of specific subgroups.

It may be that patients who undergo angiocardiography are at higher risk of renal dysfunction resulting from hypotension, arrhythmias, myocardial infarction, atheroemboli, (11-13) and use of nephrotoxic medications, all of which are less likely to occur in patients undergoing CECT.
They then discuss acquisition and processing protocols, as well as imaging display and analysis for SPECT myocardial perfusion imaging, planar myocardial perfusion imaging, planar equilibrium radionuclide angiocardiography, and SPECT equilibrium angiocardiography.
MRI is particularly useful in diagnosing specific tracheobronchial abnormalities, and it is now preferred to the more invasive angiocardiography. (2) Spiral computed tomography and three-dimensional image reconstruction are other noninvasive techniques used in the diagnosis and evaluation of vascular rings.

However, systematic assessments of the LV function and size, MR, and complications of patients with ALCAPA managed with left coronary artery (LCA) re-implantation are limited.[sup][4] Although coronary computed tomography angiography, magnetic resonance imaging (MRI), and invasive angiocardiography are used for the diagnosis of ALCAPA, echocardiography still is harmless and inexpensive and is the most frequently used method at present.
included 929 patients receiving either HOCM or LOCM when undergoing diagnostic angiocardiography or contrast enhanced body CT [40].
Although contrast angiocardiography would be required for definitive diagnosis, this defect was considered highly unlikely.
