目的:探讨在乳腺癌早期筛查中应用乳腺钼靶联合彩色多普勒超声检查的价值.方法:本研究选取2017.01～2020.06之间本院手术病理确诊为早期乳腺癌患者,总共80例,回顾性分析其相关资料,全部患者均接受乳腺钼靶、彩超检查.金标准以病理结果为准,对比不同方式诊断特异度、敏感度、准确性.结果:比较彩超、钼靶及二者联合诊断早期乳腺癌,其结果具有统计学意义(P＜0.05).在特异度、敏感度、准确度上,彩超分别为50.0％、70.31％、66.25％,乳腺钼靶分别为68.75％、79.69％、77.5％,联合检查分“,”Objective: To explore the value of mammography combined with color Doppler ultrasonography in the early screening of breast cancer. Methods: From January 2017 to June 2020,80 cases of early breast cancer were diagnosed by operation and pathology in our hospital. All patients underwent mammography and color doppler ultrasound. The diagnostic specificity, sensitivity and accuracy of different methods were compared. Results: The results of color doppler ultrasound, molybdenum target and their combined diagnosis of early breast cancer were statistically significant (p ＜ 0.05) .In specificity, sensitivity and accuracy, color doppler ultrasound was 50.0％ , 70.31％ , 66.25％ , mammography was 68.75％ , 79.69％ , 77.5％ , combined examination was 81.25％ , 95.31％ , 92.5％ respectively. The combined examination was superior to the color doppler ultrasound and molybdenum target examination alone in the diagnosis of early breast cancer. Conclusion: The application of molybdenum mammography combined with color ultrasound in the early screening of breast cancer has a significant effect, which can improve the specificity, sensitivity and accuracy of diagnosis, and can be further applied and popularized.
