钼靶X射线与超声诊断乳腺癌的影像学特征分析及联合应用的临床价值

Comparison of the imaging features and clinical value of mammographic X-ray and ultrasonography in the diagnosis of breast cancer

目的:比较钼靶X射线与超声诊断乳腺癌的影像学特征及临床价值。方法:选取2008年1月至2016年10月进行诊治的疑似乳腺癌女性患者160例,所有患者术前均经钼靶X射线检查和超声检查,并与病理诊断结果进行对照分析。分析不同检查方式的诊断正确指数,误诊率及漏诊率。结果:钼靶X射线和超声检查诊断的正确指数、漏诊率差异无统计学意义,而采用钼靶X线+超声的联合诊断方式,与单独钼靶X线检查及超声检查相比,真实性提高(χ2钼靶X线=8.634,P=0.016)(χ2超声=9.243,P=0.011),漏诊率降低(χ2钼靶X线=13.240,P=0.000)(χ2超声=14.536,P=0.000)。结论:在乳腺癌的诊断中,钼靶X线与超声均具有一定的诊断价值,可根据患者的情况进行针对性的选择,采取联合诊断的方式则能够提高诊断的准确性。

Objective：To compare the imaging features and clinical value of mammographic X - ray and ultrasonography in the diagnosis of breast cancer. Methods ：160 patients with breast cancer from January 2008 to October 2016 in our hospital were selected. All patients were exam- ined by mammographic X - ray and ultrasonography before operation and the results were compared with the pathological diagnosis. The diagnostic accuracy, the rate of misdiagnosis and the rate of missed diagnosis were analyzed. Results ： There were no statistical significances in the diagnostic accuracy and the rate of missed diagnosis between mammographic X -ray and uhrasonography（ P 〉 0.05 ）. Compared with mammographic X - ray and uhrasonography, the combination of mammographic X - ray and ultrasonography was accurate （ χ^2 mammographic X - ray = 8. 634, P = 0. 016）, （χ^2 ultrasonography = 9. 243, P = 0.011 ） with lower rate of missed diagnosis （χ^2 mammographic X - ray = 13. 240, P = 0. 000 ） （ χ^2 ultrasonography = 14. 536, P = 0. 000）. Conclusion：In the diagnosis of breast cancer, both mammographic X -ray and ultrasonography have certain diagnostic values. According to the patient＇s situation for targeted choice, combined diagnosis can improve the accuracy of diagnosis.
