A method of in vivo calculation of liver volume using a gamma camera and a 1600 or 4096 channel analyser is described. Topographically, the maximum thickness giving the highest counts in matrix data in the right anterior oblique projection is measured as the maximum breadth in the right posterior oblique projection. Then the total counts given by the liver can be transformed to the volume. The necropsy criteria indicated that the errors were between --11-9 +/- 14-7% in 13 cases by the use of 198Au-colloid. In 20 selected normal control subjects, the mean of measured liver volumes was 779 +/- 99 cm3/m2 of surface area. The volumetric calculation using 99mTc-Sn-colloid or 99mTc-phytate was compared with 198Au-colloid in the same patients. The results with 99mTc-Sn-colloid were well correlated with those with 198Au-colloid, but the results with 99mTc-phytate and 198Au-colloid were almost equal. It was concluded that, excluding rare severe cases of liver cirrhosis, liver volume can be measured with reasonable accuracy.
描述了一种使用γ相机和1600或4096通道分析仪在体内计算肝脏体积的方法。在地形学上，将右前斜位投影中矩阵数据中计数最高的最大厚度测量为右后斜位投影中的最大宽度。然后可以将肝脏给出的总计数转换为体积。尸检标准表明，使用198Au胶体时，13例病例的误差在-11.9±14.7%之间。在20名选定的正常对照受试者中，测量的肝脏体积平均值为779±99 cm³/ m²表面积。在同一患者中，将使用99mTc-Sn胶体或99mTc-植酸盐的体积计算与198Au胶体进行了比较。99mTc-Sn胶体的结果与198Au胶体的结果相关性良好，但99mTc-植酸盐和198Au胶体的结果几乎相等。得出的结论是，除了罕见的严重肝硬化病例外，可以以合理的准确度测量肝脏体积。
