目的比较彩超、MRI及二者联合 在乳腺肿瘤临床诊断中的应用价值。方 法 选择我院2012年4月-2015年4月期间 经手术及病理检查确诊的乳腺肿瘤患者 63例作为研究对象，分别行彩超检查及 MRI检查，比较诊断准确率。结果 联合 诊断准确率最高，为95.2%，彩超与MRI 分别为82.5%、84.1%，其中彩超与MRI的 比较无统计学意义(χ2 =0.057，P=0.811 ＞0.05)；彩超与联合诊断的比较有统计 学意义(χ2 =5.143，P=0.023＜0.05)； MRI与联合诊断的比较有统计学意义 (χ2 =4.203，P=0.040＜0.05)，说明联合 诊断具有明显优势，诊断准确率获得大幅 提高。结论 彩超、MRI在乳腺肿瘤临床诊 断中的应用均有较大价值，但二者联合可 互相矫正，大幅提高诊断准确率，为临床 手治疗提供更准确依据。

bjective To compare the application value of color Doppler ultrasound, MRI and the combination of the two in the clinical diagnosis of breast neoplasms. Methods 63 cases of patients with breast neoplasms diagnosed by operation and pathology and admitted into the hospital during April 2012 to April 2015 were selected as the research objects. The color Doppler ultrasound examination and MRI examination were performed, respectively. The diagnostic accuracy was compared. Results The accuracy rate of combined diagnosis was the highest which was 95.2% while of color Doppler ultrasound and MRI were 82.5% and 84.1%, respectively, and the difference between color Doppler and MRI was not statistically significant (χ2 =0.057, P=0.811>0.05). The comparison between color Doppler ultrasound and the combined diagnosis was statistically significant (χ2 =5.143, P=0.023<0.05). The comparison between MRI and combined diagnosis was statistically significant (χ2 =4.203, P=0.040<0.05), which showed that combined diagnosis had obvious advantages. The diagnostic accuracy rate was greatly improved. Conclusion The application of color Doppler ultrasound and MRI in the clinical diagnosis of breast cancer is of great value, but the combination of the two can correct each other and substantially increase the diagnostic accuracy, which provides a more accurate basis for clinical treatment.
