摘　　要：目的对比彩超、钼靶、磁共振成像(MRI),分析各自优缺点,评价其诊断早期乳腺癌的价值。方法回顾性分析2014年7月至2016年7月收治的乳腺微小肿块48例患者,病理证实29例为恶性,19例为良性。从敏感度、特异度、阳性预测值、阴性预测值、误诊率、漏诊率及准确率等方面,综合彩超、钼靶、MRI进行评价。结果 3者联合使用诊断乳腺微小肿块:敏感度93.1%,特异度94.7%,阳性预测值96.4%,阴性预测值90.0%,误诊率5.3%,漏诊率6.9%,准确率93.8%。3者联合使用诊断准确率高于单独使用钼靶、彩超或MRI。结论 3种技术联用在一定程度上可弥补各自的局限性,对诊断早期乳腺癌的良恶性有重要意义。Objective Comprehensive evaluation of early breast cancer diagnosis technologies was established by contrast, to analyze the diagnostic value. Methods 48 cases of breast cancer patients from July 2014 to July 2016 were retrospective analyzed, which were confirmed by pathology, of which 29 were malignant and 19 were benign. The sensitivity, specificity, positive predictive value, negative predictive value, the rate of misdiagnosis and missed diagnosis rate and accurate rate were used for reference, and the comprehensive evaluation of color Doppler ultrasound, molybdenum target, and MRI was performed. Results The combined use of the three diagnostic technologies for small breast tumor had the following decision statistics： sensitivity 93.1%, specificity 94.7%, positive predictive value 96.4%, negative predictive value 90.0%, misdiagnosis rate 5.3%, missed diagnosis rate 6.9%, the accuracy rate 93.8%. The diagnostic accuracy of the combined use of the three technologies was higher than that of the single use of molybdenum target, ultrasound, or MRI. Conclusion The combination of the three techniques can make up for the limitations of each other, and it is of great significance for the diagnosis of early breast cancer.
