本文简述了当前国内外大肠癌同位素诊断概况,指出最近核医学发展是惊人的,几乎对所有的脏器可用放射性核素进行形态和机能的检查,唯独消化道尤其大肠癌方面诊断工作进行的很少。其主要原因是迄今为止尚未找到象胶体~(108)Au或~(131)I特异浓聚于肝或甲状腺那样特异浓聚于消化道的放射性核素。在国外,从一九六九年开始作了一些大肠癌同位素诊断工作,如用同位素标记的CEA进行放射免疫分析、用同位素标记的红细胞检测大肠癌患者大
This article outlines the current status of isotope diagnosis of colorectal cancer at home and abroad, and points out that the recent development of nuclear medicine is amazing, almost all organs available for radionuclide morphology and function checks, except for the digestive tract, especially the diagnosis of colorectal cancer Very little. The main reason for this is that so far no radionuclide has been found that specifically concentrates in the digestive tract, such as colloidal (108) Au or 131I specifically concentrated in the liver or thyroid. In foreign countries, some colorectal cancer isotope diagnostic work has been done since 1969, such as radioimmunoassay using isotope-labeled CEA and detection of colorectal cancer patients using isotope-labeled red blood cells.
