摘要 目的:探讨99mTc-DX淋巴显像在乳腺癌前哨淋巴结(SLN)定位中的临床应用,为乳腺癌SLN活检或淋巴结清扫手术提供准确的定位依据。方法:术前14~16h于肿瘤表面的皮下、肿瘤周围、肿瘤内、乳晕下等注射99mTc-DX37~74MBq,进行乳腺淋巴显像,根据放射性核素浓聚的程度确定SLN的位置,并在相应的皮肤上做出标记,术中于体表标记处用γ探测仪法结合蓝染法找出SLN,送病理检查。结果:99mTc-DX淋巴显像对SLN定位活检成功率为86.0%,假阴性率为5.1%。结论:99mTc-DXSLN显像体表定位可以准确显示SLN的部位、数目及淋巴引流情况,可用于指导术中乳腺癌SLNγ探测定位及活检手术。
