In induced bleeding experiments on dogs, 99mTc-sulfur colloid was a suitable agent for detecting the bleeding site in the small intestine, providing that the site was distant from the liver and spleen. Bleeding sites were detectable at rates as low as 0.1 ml/min. When induced in the sigmoid or descending colon, the site was demonstrated by scintigraphy with 99mTc-sulfur colloid. Unsatisfactory images were obtained in the esophagus and stomach, however, when 131I-ortho-iodohippurate or 99mTc-DTPA was used.
在对狗进行的诱发出血实验中，99mTc-硫胶体是检测小肠出血部位的合适试剂，前提是该部位远离肝脏和脾脏。出血部位的检测率低至0.1毫升/分钟。当在乙状结肠或降结肠诱发出血时，99mTc-硫胶体闪烁扫描可显示出血部位。然而，当使用131I-邻碘马尿酸或99mTc-二乙三胺五乙酸时，在食管和胃中获得的图像并不理想。
