Abstract

A standard to measure ejection fraction (EF) is the method using left ventriculogram. Recently, many radiological technologists (RTs) have opportunities to measure EF. In this study, six RTs engaging in angiocardiography examination, i.e. two experts, two experienced and two inexperienced RTs, measured EF using left ventriculograms of 72 cases (Female. 15, Mail. 57, Ages were varied from 31 to 82.). The measured values were examined on correlation and further approved by repeated measure ANOVA and T-test for multigroup. Correlations between measured values by expert RT and measured values by other RTs were observed, but there were differences among the measured values of experts, experienced and inexperienced RTs. It is considered that these results offer useful guidance for RTs to improve precision.
