作者基于胆系造影剂同蛋白结合率增高时,经肝排泄量多的原理,试用了在试管中予先同蛋白结合的胆影钠进行静脉胆系造影,取得良好效果。文章一部分内容:用~(131)碘示踪的胆影钠给59例行胆系造影,注射法30例,滴注法29例。注入造影剂后30分钟和2小时分别取血和尿,测定其内放射性。患者的肝功能均不良。检查结果见附表。不论胆系显影与否,30分钟和2小时滴注法血中造影剂浓度高于注射法(仅显影组2小时血浓度例外),不显影患者的30分钟尿中造影剂量较显影者高2～3倍。作者指出,凡尿中造影剂量高于15%者,胆系将不会显影。
Based on the principle of increased gallbladder contrast agent-protein binding rate, the principle of hepatic excretion was used to test the intravenous gallbladder bolus of gallbladder sodium pre-conjugated with protein in the test tube. Good results were obtained. Part of the article: Biliary sodium tracer labeled with ~(131) iodide was given to 59 cases of gallbladder angiography, 30 cases of injection and 29 cases of instillation. Blood and urine were collected 30 minutes and 2 hours after the injection of the contrast agent, and their internal radioactivity was measured. The patient’s liver function was poor. Check the results in the attached table. Regardless of the development of the biliary system, the concentration of contrast medium in the blood was higher than that of the injection method in the 30-minute and 2-hour instillation (except for the 2-hour blood concentration in the imaging group alone), and the 30-minute urinary contrast dose in the non-developed patient was higher than that in the developer. ~ 3 times. The authors pointed out that the biliary line will not be developed when the dose of urography is higher than 15%.
