Abstract | 「要旨」81Rb-81mKrジェネレータを用いて, 81mKrの右心機能への応用を1)安静時における再現性, 99mTc-HSA・99mTc-MAA first passのright ventricular ejection fraction(RVEF)と比較, 2)運動・薬剤併用intervention study(isosorbide dinitrate 9例, nifedipine 9例)を施行し, その有用性を確認した. 81mKrの持続注入法での再現性はy=0.92x+2.7(r=0.97, p<0.01, n=9), 99mTc-HSA・99mTc-MAAとのRVEFの相関はそれぞれ, y=0.97x-0.48(r=0.86, p<0.01, n=23), y=1.0x-1.8(r=0.96, p<0.01, n=9)であった. また運動・薬剤併用試験ではisosorbide dinitrate症例で有意なRVEFの軽減(p<0.05)を認めた. |

Abstract | To assess the availability of 81mKr using 81Rb-81mKr generator, I studied (1) reproducibility of 81mKr-RVEF measurement, and compared 81mKr-RVEF with 99mTc-HSA- and 99mTc-MAA-RVEF first pass study, (2) intervention study-exercise stress combined with drug administration (isosorbide dinitrate, 9 cases; nifedipine, 9 cases). Reproducibility of 81mKr-RVEF measurement by continuous elution method was y=0.92x+2.7 (r=0.97, p<0.01, n=9), and correlation with RVEF of 99mTc-HSA and 99mTc-MAA were y=0.97x-0.4 (y=0.97, p<0.01, n=9), y=1.0x-1.8 (r=0.86, p<0.01, n=9) respectively. Furthermore, ΔRVEF during bicycle exercise was increased significantly (p<0.05) at 50 watts between pre- and post-isosorbide dinitrate administration. |
