99mTc-MDP核素显像诊断乳腺肿瘤的临床价值

目的 寻找有效和无创性诊断乳腺癌的方法。方法 对可触及的７５例乳腺肿瘤进行了＾９９ｍＴｃ－ＭＤＰ显像，将其结果与乳腺Ｘ线摄像和Ｂ超对比分析，全部肿瘤经病理或细胞学证实。结果 ７５例乳腺肿瘤中５０例为乳腺癌，２５例为良性肿瘤。＾９９ｍＴｃ－ＭＤＰ显像诊断乳腺肿瘤假阳性５例，假阴性５例，其灵敏度为９０％（４５／５０），特异性为８０％（２０／２５），准确性为８７％（６５／７５）；６２例乳腺肿瘤行Ｘ线摄像

99mTc-MDP scintimammography imaging for diagnosing breast tumors

Objectvie To evaluate 99m Tc-MDP scintimammography as an effective and noninvasive modality in differentiating benign from malignant breast tumors.Methods 99m Tc-MDP scintimammography was performed in 75 women with palpable breast masses.All pathological results were obtained by excisional biopsy or fine needle aspiration. Results 99m Tc-MDP scintimammography was positive in 45 of 50 breast carcinoma and 5 of 25 benign breast lesions.The sensitivity and specificity were 90% and 80%,respectively.Mammography and ultrasonography had lower sensitivity and accuracy them scintimammography. Conclusion 99m Tc-MDP scintimammography is a simple, accurate and noninvasive test that differentiates malignant from benign breast lesions,particularly suitable for patients suspicious as malignant tumors by mammography.
