【摘要】 为探讨^99mTc-甲氧基异丁基异脯（MIBI）对鉴别乳腺肿物良恶性的临床价值,对125例患乳腺肿物的病人进行^99mTc-MIBI 平面显像及半定量分析,均与病理检查结果对照,部分病例与红外线、钼靶及针吸活组织检查结果对照。结果:此方法鉴别乳腺肿物良恶性的灵敏度与特异性分别为90%与87%,明显高于红外线（76%与57%）、钼靶（74%与82%）及针吸（66%与100%）。故^99mTc-MIBI 平面显像半定量分析是术前筛选和鉴别乳腺肿物良恶性的较好方法。更多还原

【Abstract】 PURPOSE To discuss the clinical value of ^99mTc-MIBI planar imaging in differentiating the benign and malignant breast tumor.METHODS 125 patients with breast tumor were examined by ^99mTc-MIBI planar imaging and semiquantitative analysis was performed.All the results were compared with pathologic study and some were compared with ultra-red scanning, mammography and fine-needle aspiration cytology.RESULTS The sensitivity of ^99mTc-MIBI imaging was 90% and the specificity was 87%,much higher than those of ultra-red scanning （76%,57%）,mammography （74%,82%）,and fine-needle aspiration cytology （66%,100%）.CONCLUSIONS Semiquantitation in ^99mTc-MIBI planar imaging is a good method for preoperative screening and malignancy differentiation in breast tumors.更多还原
