Relative renal uptake of 99mTc-dimercaptosuccinic acid (DMSA) was compared with the relative effective renal plasma flow (ERPF) to each kidney. In 25 patients with serum creatinine less than or equal to 2.0 mg/dl, there was excellent agreement when the regions of interest were assigned by a computer. In 10 patients with serum creatinine greater than 2.0 mg/dl, agreement was poor. A 24-hour image is sufficient to obtain such data. In patients with renal failure, this technique may give inaccurate results due to high tissue background activity; moreover, since it reflects the current functioning status of the kidney, it should not be used to predict recoverable function in patients with acute or unstable renal disease.
比较了99mTc-二巯基丁二酸（DMSA）的相对肾摄取与每个肾脏的相对有效肾血浆流量（ERPF）。在25例血清肌酐小于或等于2.0mg/dl的患者中，当通过计算机指定感兴趣区域时，两者具有极佳的一致性。在10例血清肌酐大于2.0mg/dl的患者中，一致性较差。一张24小时的图像足以获得此类数据。在肾衰竭患者中，由于组织本底活性较高，该技术可能会给出不准确的结果；此外，由于它反映的是肾脏当前的功能状态，因此不应将其用于预测急性或不稳定肾病患者的可恢复功能。
