Comparison of the blood clearances of 51Cr-EDTA and 99Tcm-Sn-DTPA, in a series of 45 patients with a wide range of glomerular filtration rates, showed that there was a good correlation between the estimates of G.F.R. obtained using the two chelates simultaneously. The single-injection, single-exponential method of G.F.R. estimation was used, with a correction factor of 0.964 for 99Tcm-DTPA, which gave a relationship of G.F.R.Cr = 2.3+G.F.R.Tcml/min with a correlation coefficient of 0.99. 99Tcm-DTPA is a suitable agent for the estimation of glomerular filtration rate.
对45例肾小球滤过率范围广泛的患者进行的一项研究，比较了51Cr-EDTA和99Tcm-Sn-DTPA的血液清除率，结果显示，同时使用这两种螯合物获得的肾小球滤过率（G.F.R.）估计值之间具有良好的相关性。采用单次注射、单指数法估计G.F.R.，99Tcm-DTPA的校正因子为0.964，得出G.F.R.Cr = 2.3 + G.F.R.Tcml/min的关系，相关系数为0.99。99Tcm-DTPA是一种适用于估计肾小球滤过率的试剂。
