| Abstract | [Summary] To evaluate the usefulness of 133Xe-RVEF (right ventricular ejection fraction), 133Xe (20 mCi) was injected intravenously and compared with 81mKr-RVEF and 99mTc-HSA-RVEF. Reproducibility of 133Xe-RVEF was a good correlation (y=0.91x+4.0, r=0.92, p<0.01, n=16), and 133Xe-RVEF were correlated significantly with 99mTc-HSA-RVEF and 81mKr-RVEF (y=0.64x+14.4 (r=0.75, p<0.05, n=10), y=0.68x+9.3 (r=0.80, p<0.05, n=8)), respectively. 133Xe-RVEF study will be of use to evaluate the right ventricular intervention. |
