A new model is proposed for the quantitative analysis of segmental left ventricular wall motion from contrast left ventriculograms and scintigraphic cardiac-gated blood-pool images. This model was tested in dogs using implanted lead beads in the myocardium and contrast left ventriculography. Measured values of bead position and displacement were in good agreement with the estimated values determined by the model. Segmental left ventricular wall motion was also measured in 21 patients in whom both cardiac-gated blood-pool scintigrams and contrast left ventriculograms were obtained within minutes of one another. Wall motion values obtained using the end diastolic and end systolic frames of the gated blood-pool studies and the contrast left ventriculograms correlated favorably in the 60 degrees left anterior oblique view. |
