Abstract

Images of the kidneys at 1-2 min after injection in [123I]hippuran gamma camera renography were used to find the functional renal volume. The method consists of a summation of the small volumes represented by each pixel in the activity images of the kidneys stored in the computer. In principle, the functional renal volume can therefore be calculated for any renal shape but the paper deals predominantly with normal kidneys. The method described is a by-product of gamma camera renography and is considered valuable for monitoring kidney growth in the normal child. It is believed that the method is also useful for determination of normal/pathological renal volume in patients with renal diseases who have normal/quasi-normal renal shapes.

摘要

在[123I]马尿酸γ相机肾造影中，注射后1 - 2分钟的肾脏图像用于确定功能性肾体积。该方法是对计算机中存储的肾脏活性图像中每个像素所代表的小体积进行求和。因此，原则上可以针对任何肾脏形状计算功能性肾体积，但本文主要讨论的是正常肾脏。所描述的方法是γ相机肾造影的一个副产品，被认为对于监测正常儿童的肾脏生长很有价值。据信，该方法对于确定肾脏形状正常/接近正常的肾病患者的正常/病理肾体积也很有用。
