摘　　要：肾小球滤过率 (GFR)是评价肾脏功能的重要指标 ,99锝 二乙三胺五乙酸 ( 99Tcm DTPA)肾动态显像是临床最常用的测定GFR的检查方法。但多种因素可能影响测定结果 ,如99Tcm DTPA与血浆蛋白的结合、感兴趣区、本底、肾脏深度、病人的年龄等。Glomerular filtration rate (GFR) is an important criterion to estimate renal function, and 99 Tc m-DTPA dynamic renal imaging is most often applied clinical method to measure GFR. However, in clinical practice, the result may be influenced by various elements, such as protein binding of 99 Tc m-DTPA, region of interest area, the background, kidney depth, patients' ages, and so on. This article is a comprehensive review of those elements.
