Left ventricular volumes by gated equilibrium radionuclide angiography: a new method.
To compare radionuclide end-diastolic (EDV) and end-systolic (ESV) volumes with angiographic volume, we studied 52 patients with equilibrium radionuclide angiography using 99mTc-human serum albumin within 48 hours of contrast angiography. Each RR interval was divided into 20--28 equally timed frames and a time-activity curve generated. End-diastolic counts were taken at the early peak of the cu...
متن کاملNoninvasive quantitation of valvular regurgitation by gated equilibrium radionuclide angiography.
R-wave synchronous equilbrium radionuclide angiography (RNA) is a noninvasive method that provides time-activity curve count information proportional to ventricular volumes and is used for relative volume comparisons within the left or right ventricle to derive the ejection fraction. Comparison of the ventricular count output between both ventricles may permit quantitation of the relative amoun...
متن کاملNoninvasive quantitation of right-ventricular volume overload in adults by gated equilibrium radionuclide angiography.
R-wave-synchronized equilibrium radionuclide angiography (RNA) is a noninvasive method whose time-activity curves provide count information that is proportional to ventricular volume. We have performed resting gated RNA in nine consecutive adult patients undergoing cardiac catheterization for evaluation of left-to-right shunting. Pulmonary/systemic flow ratios (Qp/Qs) calculated from RNA correl...
متن کاملA method for the estimation of right ventricular volume by equilibrium radionuclide angiography.
To develop a method for estimating right ventricular volume and to assess right ventricular volume at rest, we studied 45 persons with equilibrium radionuclide angiography. The study group comprised 15 normal control subjects (5 with atypical chest pain and normal coronary angiograms) and 30 patients with coronary heart disease (CHD). Each coronary patient and 5/15 control subjects had both rig...
متن کاملResponse of left ventricular volume to exercise in man assessed by radionuclide equilibrium angiography.
To assess the effects of exercise on left ventricular volumes we studied 10 normal men, 15 patients with coronary disease who developed angina pectoris during exercise, and 10 patients with known coronary disease who did not develop angina during exercise. Each subject performed supine bicycle exercise under a mobile, single-crystal scintillation camera until angina or fatigue occurred. Technet...
