99mTc-tetrofosmin显像与超声检查在乳腺癌鉴别诊断中的价值比较

目的 探讨99mTc-tetrofosmin(99mTc-TF)平面显像、断层显像诊断乳腺癌的临床价值,并与超声检查做比较.方法 50例女性受检者均行99mTc-TF平面显像、断层显像及超声检查.以病理结果为金标准,探讨并比较99mTc-TF平面显像、断层显像及超声检查在乳腺癌良恶性鉴别诊断中的价值.结果 99mTc-TF平面、断层显像和超声检查诊断乳腺癌的灵敏度分别为74.2%、93.5%、87.1%,特异性为66.7%、73.3%、80%.结论 99mTc-TF显像尤其是断层显像是一种新的有效诊断乳腺癌的方法,可与超声检查相媲美.

Clinical value of ~(99m)Tc-tetrofosmin imaging and ultrasonography in diagnosis of breast cancer:a comparative study

OBJECTIVE: To assess the clinical value of (99m)Tc-tetrofosmin ((99m)Tc-TF) planar and single-photon emission computed tomography (SPECT) in comparison with ultrasonography in the diagnosis of breast cancer. METHODS: Fifty women underwent (99m)Tc-TF planar imaging, SPECT and ultrasonographic examinations, and with the results of histopathological examination as the golden standard, the diagnostic value of the 3 modalities were compared in the detection of malignancies of the breast neoplasms. RESULTS: The sensitivity of planar imaging, SPECT and ultrasonography in breast cancer diagnosis was 74.2%, 93.5%, and 87.1%, with specificity of 66.7%, 77.3%, and 80.0%, respectively. CONCLUSION: (99m)Tc-TF imaging is a new and effective method for diagnosis of breast cancer.
