简介：目的：评价^99Tc^m-MIBI乳腺显像对乳腺肿瘤和腋窝淋巴结转移的诊断价值。方法：52例女性乳腺肿瘤患者，体检腋窝未扪及肿块。应用^99Tc^m-MIBI740MBq(20mCi)经肘静脉注射，行乳腺和腋窝显像，并用手术、病理加以对照。结果：48例乳腺肿瘤患者中，^99Tc^m-MIBI显像真阳性32例，灵敏度为84％(32／38例)，特异性60％(6／10例)，准确性79%，40例乳腺癌腋窝淋巴结的灵敏度为71％(10／14例)，特异性88％(23／26例)，准确性83％。结论：^99Tc^m-MIBI乳腺显像既可以显示乳腺肿瘤又能了解腋窝淋巴结的灵敏度为71％(10／14例)，特异性88％(23／26例)，准确性83％。结论：^99Tc^m-MIBI乳腺显像既可以显示乳腺肿瘤又能了解腋窝淋巴结，是核素乳腺显像的首选方法之一。
