寻找亲肿瘤显像的阳性扫描剂是早期探测肿瘤的重要环节。过去通常采用各种标记化合物或亲肿瘤核素,~(67)Ga被认为是较理想的亲肿瘤核素之一。虽其阳性率较高,但常在炎症部位积聚而导致假阳性。近年来,由于杂交瘤技术的问世和逐步完善,成功地制备出了各种特异的单克隆抗体(简称McAb),为肿瘤的诊断和治疗提供了新的手段。 Looking for positive tumor imaging scans is an important part of the early detection of tumors. In the past, a variety of labeled compounds or pro-tumor nuclides were commonly used, and ~ (67) Ga was considered as one of the more ideal tumor nuclides. Although the positive rate is high, but often in the accumulation of inflammation caused false positive. In recent years, due to the advent of the hybridoma technology and the gradual improvement of the successful preparation of a variety of specific monoclonal antibody (McAb), for the diagnosis and treatment of cancer provides a new means.
