目的 探讨超声和磁共振联合应 用在乳腺良恶性结节中的诊断价值。方法 收集63例68个结节的彩色多普勒超声和磁 共振影像资料，并将诊断结果与病理结果 进行对照，分析两者的诊断优势。结果 本组中病理诊断为良性30个结节，恶性38 个，其中超声诊断敏感度为97.14%，特异 度为80%，准确性为83.33%，MR敏感度为 100%，特异度为50%，准确性为83.33%， 两者结合可提高诊断的准确性，准确性可 达88.88%。结论 彩色多普勒超声与磁共 振增强扫描联合应用能提高乳腺良恶性病 变的检出率，为乳腺癌早期诊断提供更为 可靠的诊断依据。

Objective To discusses the application value of ultrasound and magnetic resonance (MR) diagnostic in breast benign and malignant nodules. Methods 68 nodes with color doppler ultrasonography and magnetic resonance imaging were collected, which were compared with the pathology results, to analyze the diagnostic advantage. Results pathologic 30 nodules were benign and 38 malignant were confirmed by pathology. Ultrasonic diagnostic sensitivity was 97.14%, specific degrees was 80%, the accuracy was 83.33%, MR sensitivity was 100%, specific degrees was 50%, the accuracy was 83.33%, the combined application of the two way could improve the diagnostic accuracy, which could reach 88.88%. Conclusion The combined application of color doppler ultrasound and MRI enhancement scanning can improve the detection rate of breast benign and malignant lesions, provide more reliable diagnostic basis for early diagnosis of breast cancer.
