- Abstract:
- 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.
