METHODS Nine consecutive subjects were studied at rest. Each sub ject's red blood cells
were labeled (in vivo) with 20 mCi technetium-99m, preparatory to a standard ECG gated …

The geometrical independence of radionuclide techniques for the measurement of left
ventricular ejection fraction is commonly quoted. The authors have shown this to be …

Ejection fraction (EF) and ventricular volume curves obtained using various combination of
scinticamera and computer systems were compared. A dynamic cardiac phantom …

The measurement of ejection fraction (EF) by the of tissue, sothat a gradient indetector
sensitivity exists radionuclide angiographie (RA) technique is based on along the line of …

The scintigraphic determination of the left ventricular ejection fraction (EF) is derived either
from first pass data or from ECG gated equilibrium studies. The values obtained by either …

A miniature, non-imaging caesium iodide nuclear probe optically coupled to a photodiode
(the'Cardioscint') has been developed which, in conjunction with a modified personal …

The left ventricular ejection fractions of 53 patients were determined from multi-image
cardiac blood pool scintigrams in the left anterior oblique position utilizing a microcomputer …

Dynamic cardiac phantoms and radionuclide imaging were used to obtain ejection fraction
(EF) and left ventricular (LV) volume measurements. Tc-99m pertechnetate and water …

[en] Single photon transaxial emission tomography was used to assess left ventricular
function in 30 patients. A conventional gated cardiac blood pool investigation was performed …

A method which does not require an online computer has been developed to measure left
ventricular ejection fraction from a bolus of 99m Tc-pertechnetate. The passage of the bolus …
