In many subjects, overlap of the image of the pancreas by the liver image makes clear delineation of the pancreas uncertain. A dual isotope technique was evolved with a ratio substract system. Experiments in vitro with a phantom liver and pancreas successfully erased the liver image from the final printout. In vivo, however, the results were in many cases unsatisfactory. A detailed statistical analysis of the data has provided an explanation for these differences.
在许多受试者中，肝脏图像与胰腺图像重叠，使得胰腺的清晰勾勒变得不确定。一种双同位素技术与比率减法系统应运而生。使用模拟肝脏和胰腺的体外实验成功地从最终打印结果中消除了肝脏图像。然而，在体内实验中，许多情况下结果并不理想。对数据进行的详细统计分析为这些差异提供了解释。
