超声与MRI诊断乳腺癌及不同病理分型影像特点分析

探讨超声与MRI诊断乳腺癌的效果及不同病理分型影像特点。方法:比较分析112例疑似乳腺癌表现患者的超声、MRI及联合检查诊断效果及病理分型情况。结果:超声、MRI及联合诊断对乳腺癌的检出率并无统计学差异（90.36% vs 95.18% vs 98.80%, P>0.05）；联合诊断漏诊率和误诊率均显著低于超声诊断（1.79% vs 13.39%，0.89% vs 6.25%, P<0.05）；联合诊断灵敏度、特异度、准确率、阳性预测值、阴性预测值均显著高于超声诊断（97.59% vs 81.93%, 96.55% vs 75.86%, 97.32% vs 80.36%, 98.78% vs 90.67%, 93.33% vs 59.46%, P<0.05）；联合诊断准确率显著高于MRI诊断（97.32% vs 89.29%, 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判断提供良好依据。

Effectiveness of ultrasound and MRI in the diagnosis of breast cancers and analysis of imaging features of different pathological types

Abstract: Objective To evaluate the effectiveness of ultrasound and magnetic resonance imaging (MRI) in the diagnosis of breast cancers, and analyze the image features of different pathological types of breast cancers. Methods A total of 112 patients with suspected breast cancer were examined by color Doppler ultrasound, MRI, or color Doppler ultrasound + MRI. The diagnosis results and pathological types were analyzed. Results No significant differences were found in the detection rate of breast cancer among color Doppler ultrasound group, MRI group and color Doppler ultrasound + MRI group (90.36% vs 95.18% vs 98.80%, P>0.05). The rates of missed diagnosis and misdiagnosis in color Doppler ultrasound + MRI group were lower than those in color Doppler ultrasound group (1.79% vs 13.39%, 0.89% vs 6.25%, P<0.05). The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of color doppler ultrasound + MRI were higher than those of color Doppler ultrasound (97.59% vs 81.93%, 96.55% vs 75.86%, 97.32% vs 80.36%, 98.78% vs 90.67%, 93.33% vs 59.46%, P<0.05). Moreover, the diagnostic accuracy of color Doppler ultrasound + MRI was higher than that of MRI (97.32% vs 89.29%, P<0.05). The image features of color Doppler ultrasound and MRI images had some connections with the pathological type, and a high coincidence rate was found between image features and pathological results. Conclusion Using the combination of color Doppler ultrasound with MRI to diagnose breast cancer can improve the diagnostic accuracy. The image features obtained by color Doppler ultrasound and MRI can provide good evidence for diagnosing breast cancers and determining pathological types.
