目的 :探讨99mTc tetrofosmin乳腺扫描在鉴别可扪及的乳腺包块良恶性病变中的价值。方法 :采用前瞻性同步盲法。 2 0 0 0年 6月～ 2 0 0 1年 1 2月在我院临床发现乳腺包块的 1 0 1例患者接受SPECT乳腺扫描 ,并与针吸细胞学检察 ,乳腺X片和乳房彩色多谱勒检查进行了对比。全部病例进行了手术 ,以术后病理结果为标准。以四格表进行评价分析。结果 :99mTc tetrofosmin在对可扪及的乳腺包块性质进行鉴别诊断时 ,特异性 84.0 % ,敏感性 86 .3 % ,准确性 85 .1 % ,阳性预测值 84.6 % ,阴性预测值 85 .7%。结论 :99mTc tetrofosmin在对可扪及的乳腺包块进行良恶性质的鉴别时 ,不失为一种方便且较为准确的方法
Objective: To investigate the value of 99mTc tetrofosmin breast scanning in the differential diagnosis of benign and malignant breast masses. Methods: A prospective synchronized blind method was used. One hundred and ten patients with breast mass in our hospital from June 2000 to January 2001 were screened by SPECT and compared with aspiration cytology, X-ray and breast color Le son check the contrast. All patients underwent surgery, with postoperative pathological results as the standard. Four grids for evaluation analysis. Results: 99mTc tetrofosmin had a specificity of 84.0%, sensitivity 86.3%, accuracy 85.1%, positive predictive value 84.6% and negative predictive value 85.7 in the differential diagnosis of palpable breast masses %. CONCLUSIONS: 99mTc tetrofosmin is a convenient and accurate method for differentiating benign and malignant masses of palpable breast mass
