早在1923年 A.W.Fisher 就首次介绍了结肠双重对比造影技术。但在六十年代以前这一技术发展比较缓慢,诊断准确性提高不快,临床应用也不够普遍。近十余年来其发展比较迅速。在病人的准备、钡悬液的配制、造影方法以及辅助药物的应用等方面都有了不少的创新和改进。现在这一技术已在日本、欧美得到广泛的应用,其检查效果很好,可与纤维结肠镜比美。因此,在国外 As early as 1923, A.W. Fisher first introduced the colonic double contrast radiography. However, prior to the 1960s, the technology developed slowly, the accuracy of diagnosis was not improved, and clinical application was not universal enough. In the past ten years, its development has been relatively rapid. In the patient’s preparation, the preparation of barium suspension, contrast method and the application of auxiliary drugs and so has a lot of innovation and improvement. Now this technology has been widely used in Japan, Europe and the United States, its examination is very good, with the colonoscopy than the United States. Therefore, in foreign countries
