A new method of combined serial scintigraphy and renography, using a scintillation camera and 99mTc-DTPA is evaluated. Renographic curves, corresponding to light-pen "areas of interest" over the renal parenchyma, were processed. "Blood-background" curves were recorded from an external detector over the temporal region of the head and also from an "area of interest" corresponding to the aorta and inferior vena cava. The uptake phase of the renogram was always linear. The sum of the slopes of the uptake phase of both kidneys correlated well with the measured glomerular filtration rate in 25 patients with renal insufficiency of various degrees. Single-kidney function estimated from the slopes correlated reasonably well with single-kidney function estimated from 131I-Hippuran renography with external detectors. The method described minimizes errors in the estimation of single-kidney function, and both anatomic and functional information is obtained.
对一种使用闪烁相机和99mTc-DTPA的联合串行闪烁扫描术和肾造影术的新方法进行了评估。处理了与肾实质上方光笔“感兴趣区域”相对应的肾造影曲线。从头部颞区上方的外部探测器以及与主动脉和下腔静脉相对应的“感兴趣区域”记录“血液本底”曲线。肾图的摄取期始终呈线性。在25例不同程度肾功能不全的患者中，双肾摄取期斜率之和与测得的肾小球滤过率相关性良好。根据斜率估算的单肾功能与使用外部探测器通过131I-马尿酸肾造影术估算的单肾功能相关性较好。所描述的方法将单肾功能估计中的误差降至最低，并且可同时获得解剖学和功能信息。
