Apparent volumes of distribution of 51Cr-EDTA and 99Tcm-DTPA were calculated three hours after intravenous injection and correlated with simultaneous estimation of GFR. A reasonable correlation between these values was obtained for those patients with GFR greater than 50 ml/min (standard error of estimate using 51Cr-EDTA 7.6 ml/min and 99Tcm-DTPA 13.7 ml/min). Theoretical reasons are given why a single sample technique will not be accurate over a wide range of renal function.
静脉注射后三小时计算51铬-依地酸二钠和99锝-二乙三胺五乙酸的表观分布容积，并与同时估算的肾小球滤过率相关。对于肾小球滤过率大于50毫升/分钟的患者，这些值之间获得了合理的相关性（使用51铬-依地酸二钠估算的标准误差为7.6毫升/分钟，使用99锝-二乙三胺五乙酸估算的标准误差为13.7毫升/分钟）。文中给出了理论原因，解释了为什么单样本技术在广泛的肾功能范围内不准确。
