肿瘤相关抗原的发现及其抗体的制备,在肿瘤显像领域揭开了新的篇章。人们利用特异性极高的抗原抗体反应和使用放射性核素标记抗肿瘤抗体,通过外显像对肿瘤进行定位,称之放射免疫定位(Radioimmunolocalisation,RIL)。这种方法原则上和常规显像的方法有所不同,后者一般取决于所影响的组织的特异 The discovery of tumor-associated antigens and the preparation of their antibodies have opened a new chapter in the field of tumor imaging. The use of highly specific antigen-antibody reactions and the use of radionuclides to label anti-tumor antibodies and localization of tumors by external imaging are referred to as radioimmunolocalisation (RIL). This method is different in principle from conventional imaging methods, which generally depend on the specificity of the affected tissue.
