| Abstract | 「要旨」123Iヒプル酸ナトリウムを用いてファンクショナルイメージ, 区域レノグラムを作成し臨床経過, 経静脈性腎盂造影(以下IVP), クレアチニンクリアランス(以下Ccr)値と比較することにより臨床評価を行った. 対象は尿路結石患者を主とした21例であった. ファンクショナルイメージはTmax, T1/2, 有効腎血流量(以下ERBF)の3種のパラメーターを用いて作成した. 注入後5分, 25分における血中放射能および時間放射能曲線の初期相より求めたERBFイメージは術後の腎内機能分布の変化や術後腎機能の回復をよく表わした. Tmax, T1/2イメージ, 腎盂部レノグラムは腎盂の拡張, 排泄の遅延などのIVP所見との間に相関を示した. 実質部レノグラムのTmaxによる腎機能評価はCcr値とは相関せず, また関心領域のとり方によりTmaxが変動するため, 腎機能評価には区域レノグラムだけでなくファンクショナルイメージを加えて判断する必要があると思われた. |

| Abstract | [Summary]Functional images and regional renograms using I-123 OIH were evaluated by comparing with patients' clinical courses, intravenous pyelographies and Creatinine clearances. Twenty-one patients with obstructive uropathy were studied. Functional images were processed in three parameters of Tmax, T 1/2 and ERBF (effective renal blood flow). ERBF images were composed of regional counts in early blood flow phase of renograms. Regional renograms were produced on renal parenchyma and pelvis. ERBF images represented the functioning distributions of renal tissue after the surgery and the recoveries in the renal parenchyma. Tmax and T 1/2 images and pelvic regional renograms showed the good correlations with IVP findings which presented the dilatation of pelvis and the delay of excretion. Parenchymal regional renograms showed the poor correlations with Creatinine clearances and caused sometimes errors in ROI settings. The evaluation of renal function only by the parenchymal regional renogram seemed to be inappropriated. |
