为探讨~(99m)Tc-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~(99m)Tc-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~(99m)Tc-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。 To investigate the clinical value of ~ (99m) Tc-methoxyisobutylmethylene (MIBI) in differentiating benign and malignant breast tumors, 125 patients with breast masses underwent 99m Tc-MIBI planar imaging and half Quantitative analysis were compared with the pathological examination results, some cases with infrared, mammography and needle biopsy results. Results: The sensitivity and specificity of this method in distinguishing benign and malignant breast tumors were 90% and 87%, respectively, which were significantly higher than those of infrared (76% and 57%), mammography (74% and 82% With 100%). Therefore, ~ (99m) Tc-MIBI semi-quantitative analysis of planar imaging is a good preoperative screening and identification of benign and malignant breast tumor better way.
