摘要: Multiple-gated acquisition (MUGA) blood-pool ventriculography has been established as a useful non-invasive method to evaluate ventricular size and function [1–5]. Phase image analysis, computer-derived obtained by application of temporal Fourier analysis [6, 7] the ECG-gated study, recently expanded information gained from this procedure. is based upon interrelationship time versus radioactivity curves among 4,096 picture elements (pixels) comprising overall ventriculogram. Thus, phase creates visual pattern emptying. In absence severe mechanical abnormalities, contraction follows conduction [8], displays intraventricular [9, 10].
