First-pass or single-pass radionuclide angiography evaluation of left ventricular ejection fraction using a microcomputer system.
Left ventricular ejection fractions of 31 patients determined from first-pass or single-pass radionuclide angiography from the anterior position using a microcomputer system and floppy disc were compared to angiographic catheterization data obtained from the right anterior oblique position. This study demonstrated a good correlation with r = 0.91. To our knowledge, this is the first report of comparative first-pass left ventricular ejection fraction data and contrast angiography using a microcomputer system and a floppy disc.
