目的 探讨超声与MRI联合诊断乳 腺癌及其病理分型中的效果。方法 比较 分析81例疑似乳腺癌的患者超声、MRI及 联合检查的诊断效果以及病理分型情况。 结果 超声联合MRI检查乳腺癌诊断率显著 高于超声检查，漏诊率显著低于超声检查 (P＜0.05)；超声联合MRI检查诊断率、漏 诊率、误诊率与MRI检查并无统计学差异 (P＞0.05)；超声联合MRI检查灵敏度、准 确率、阴性预测值均显著高于超声检查， 准确率显著高于MRI检查(P＜0.05)；超声 与MRI图像特征与病理分型有一定联系， 二者与手术病理结果符合率较高。结论 超声与MRI联合诊断乳腺癌能够提高诊断 准确率，二者图像特征能够为乳腺癌诊断 和病理分型提供依据。

Objective To evaluate the results of ultrasonography combined with MRI in diagnosis of breast cancer and its pathological classification. Methods A total of 81 cases of patients suspected of breast cancer were examined by color doppler ultrasound, MRI, or color doppler ultrasound combined with MRI. The diagnosis and pathological type were analyzed. Results The diagnostic rate of breast cancer for the color doppler ultrasound combined with MRI group were higher than the color doppler ultrasound group, and the omission diagnostic rate were lower than the color doppler ultrasound group(P ＜0.05), there were no significant difference on the diagnostic rate, omission diagnostic rate and misdiagnosis rate between the color doppler ultrasound combined with MRI group and MRI group(P＞0.05), the sensitivity, accuracy, negative predictive value of the color doppler ultrasound combined with MRI group were higher than the color doppler ultrasound group, and the accuracy were higher than the MRI group(P＜0.05), the image feature of color doppler ultrasound and MRI were had some connection with pathological type, and the coincidence rate of image feature and surgical pathology was high. Conclusion It has high accuracy in breast cancer by color doppler ultrasound with MRI. The image feature of color doppler ultrasound and MRI can provide good evidence for the diagnosis of the breast cancer.
