Quantitative radionuclide angiocardiography: determination of Qp: Qs in children.
A new method of determining pulmonary-to-systemic flow ratios (Qp/Qs) in patients with left-to-right shunts using radionuclide angiocardiography is described. It involves the analysis of pulmonary time-activity histograms using a gamma-variate model. It appears to be simple, relatively atraumatic, and superior to the methods using C2/C1 ratios because, in addition to accurately detecting the pr...
متن کاملEquilibrium radionuclide angiocardiography.
Planar equilibrium radionuclide angiography (ERNA) is used to determine global and regional measures of ventricular function (primarily left ventricular [LV] function) at rest and/or during exercise stress or pharmacologic intervention. These measures of ventricular function may include evaluations of ventricular wall motion, ejection fraction (EF), and other parameters of systolic and diastoli...
متن کاملIntraventricular masses detected by radionuclide angiocardiography.
Two patients are described in whom intraventricular tumors were incidentally detected by radionuclide angiocardiography. This finding led, in one patient, to surgical cure.
متن کاملDocumentation of tricuspid regurgitation by radionuclide angiocardiography.
Review of the radionuclide cardiac angiograms of 82 patients studied during the past year showed reflux of activity down the inferior vena cava in 7, all ofwhom had clinical evidencefor or clinical conditions associated with tricuspid regurgitation. Analysis of theflow of the radioactive bolus through the cardiac chambers demonstrates that the inferior vena cava fills only after activity enters...
متن کاملQuantitative radionuclide angiocardiography. Determination of left ventricular ejection fraction in children.
A method is described for measuring left ventricular ejection fraction which uses high frequency computer recording of gamma scintillation camera data and peripheral venous injectinon of technetium-99m as sodium pertechnetate. Data from mechanical model experiments are used to show feasibility of this method. A phantom experiment is described which was used to develop a technique for accurate d...
