目的:比较彩色多普勒超声、钼靶和MRI在乳腺良恶性疾病诊断中的作用.方法:以术后病理结果为金标准,比较术前3种检查方法的诊断准确性.结果:共计465例乳腺疾病患者接受检查,其中乳腺恶性病变339例,乳腺良性病变126例.乳腺癌彩超、钼靶和MRI的灵敏度分别为88.3%、85.3%和92.3%,特异度分别为88.6%、90.4%和91.7%,诊断符合率分别为88.5%、89.5%和92.0%,其中MRI 的各项诊断指标均为最高,对≤2cm的乳腺癌,钼靶的特异度最高(96.2%),但对于<45岁的年轻女性的致密性乳腺内的病变诊断,具有较低灵敏度.对乳腺炎性病变和导管瘤,钼靶及彩超较MRI诊断率高(66.6%,66.7%).结论:彩色多普勒超声和钼靶及MRI 3种乳腺影像诊断方法对乳腺病变的诊断均有各自优势,联合三种检查方法可对术前乳腺病变有更高的诊断价值.%Objective: To compare the accuracy of color - doppler ultrasonography, mammography and MR imaging in breast disease. Methods: The diagnostic accuracy of the three methods was analyzed on the basis of post -operation pathological results. Results: Four hundreds sixty five cases ( breast cancer 339, benign lesion 126 ) were examined. Color - doppler ultrasonography, mammography and MR imaging for breast cancer, the sensitivity was respectively 88. 3% ,85. 3% and 92. 3% ,the specificity was respectively 88. 6% ,90. 4% and 91. 7% , the accuracy rates were 88. 5% ,89. 5% and 92.0% respectively. MR imaging was highest in sensitivity, specificity and accuracy.Mammography had the highest specificity in diagnosis of breast cancer( ≤2cm ), but in younger women( <45 age ), it had lower sensitivity. US and mammography had higher sensitivity than MR imaging in diagnosis of intraductal pap-illoma and inflammatory lesion of breast. Conclusion: Color - doppler ultrasonography and mammography and MRimaging are valuable breast imaging diagnostic methods.
