Following three technical problems on RI angiocardiograrhy (RI-ACG) were examined with combined use of an Anger scinticamera and VTR : 1) method and technic of RI-ACG examination by means of R-wave on ECG as a trigger. 2) applicability of an Anger scinticamera and VTR to dynamic study in terms of sensitivity, resolution, dead time and soon. 3) several problems on analysing data to estimate the left ventricular volume and the ejection fraction. This RI-ACG method is non-invasive and can be safely and repeatedly performed in severely ill patients and can give the comparable volues for SV, and EF as the cineangiographic method. Scinticamera as an apparatus on the dynamic study is expected much of good performance such as high sensitivity, resolution and short deadtime, and the computer analysis is also necessary for the dynamic study.
