| Abstract | 「要旨」131I-OIHレノグラムのretention functionをmatrix法のdeconvolutionによって求めた. 流入曲線として腹部大動脈の曲線を多項式近似によってスムージングしたものを用いた. RutlandのBBGSを行うとともにmatrix法によるdeconvolution(Piepsz)により比較的簡単に良好なretention functionが得られた. Uptake constant K(Rutland)はH(1)とよく一致した. 1〜2分値による分腎ERPFおよび30分膀胱排泄率を1〜2分値左右比に分けた分腎ERPFはH(1)とよく相関を示した. また分腎ERPFの低下例にMTT延長の傾向を認めた. |

| Abstract | [Summary]Retention function of the kidney was calculated by the deconvolution using the matrix algolithm (Piepsz). Uptake constant K (Rutland) showed a good correlation with H (1). ERPF of a single kidney which is estimated from counts at 1 to 2 minutes of the renogram or from bladder excretion rate at 30 minutes (devided to right and left kidneys by the count ratio at 1 to 2 minutes of the renogram), also correlated with H (1). In the caces of decreased ERPF, the prolongation of mean transit time was observed. |
