目的:探讨彩色多普勒超声联合MRI对小乳腺癌诊断的准确率。方法:选择2012年1月至2015年5月该院确诊为小乳腺癌的患者90例为研究对象,并均经病理确诊为小乳腺癌。90例患者均进行彩色多普勒超声检测和MRI检测,对彩色多普勒超声和MRI单独检测以及两种联合检测准确率及良恶性肿瘤的诊断情况进行比较。结果:单纯彩色多普勒超声检测的准确率为60.00%,单纯MRI检测的准确率为58.88%,联合检测的准确率为93.33%。联合检测的准确率明显高于单纯检测方法,差异有统计学意义(P<0.05)。联合检测的敏感性、特异性、阳性预测值及阴性预测值明显高于单纯彩色多普勒超声和MRI检测,比较差异有统计学意义(P<0.05)。结论:彩色多普勒超声联合MRI对小乳腺癌诊断的准确性很高,值得临床推广应用。
Objective: To investigate the diagnostic accuracy of color Doppler ultrasonography combined with MRI for small breast cancer. Methods: Ninety patients diagnosed as small breast cancer in our hospital from January 2012 to May 2015 were selected as the study subjects, all of whom were diagnosed as small breast cancer by pathology. All 90 patients underwent color Doppler ultrasound examination and MRI examination. Color Doppler ultrasound and MRI alone detection and the accuracy of the two combined detection and benign and malignant tumors were compared. Results: The accuracy of color Doppler ultrasound was 60.00%, the accuracy of MRI was 58.88%, and the accuracy of joint detection was 93.33%. The accuracy of joint detection was significantly higher than that of simple detection method, the difference was statistically significant (P <0.05). The sensitivity, specificity, positive predictive value and negative predictive value of combined detection were significantly higher than those of simple color Doppler ultrasound and MRI, the difference was statistically significant (P <0.05). Conclusion: Color Doppler ultrasound combined with MRI is very accurate in the diagnosis of small breast cancer and is worthy of clinical application.
