摘　　要：目的 探讨动态对比增强磁共振成像(DCE-MRI)联合超声多普勒、弹性成像对乳腺病变的诊断价值.方法 回顾性选取经病理证实的乳腺病变患者91例,均接受DCE-MRI、超声多普勒及弹性成像检查.分析91例乳腺良、恶性病变的影像特征,分析DCE-MRI、超声多普勒及弹性成像对良、恶性病变的诊断价值.结果 91例乳腺病变患者中良性病变62例(良性组),恶性病变29例(恶性组),2组间DCE-MRI参数、超声多普勒参数、弹性成像参数比较差异有统计学意义(P<0.05).经二元logistic回归分析,强化特点、形态、时间-信号强度曲线(TIC)、超声多普勒血流信号、弹性成像评分及应变率(SR)均为乳腺病变良、恶性的影响因素(P<0.05);三者联合鉴别诊断效能最高,敏感度为88.71%,特异度为82.76%,准确性为86.81%.结论 DCE-MRI、超声多普勒、弹性成像均能有效鉴别诊断乳腺病变,但三者联合用于鉴别乳腺病变时可进一步提高诊断效能.Objective To investigate the diagnostic value of dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)combined with Doppler ultrasound and elastography in breast lesions.Methods A total of 91 patients with breast lesions confirmed by pathology were retrospectively selected and underwent DCE-MRI,Doppler ultrasound and elastography examinations.The imaging features of benign and malignant breast lesions were analyzed.The diagnostic value of DCE-MRI,Doppler ultrasound,and elastography in benign and malignant breast lesions were analyzed.Results Among the 91 cases,there were 62 cases with benign lesions(benign group)and 29 cases with malignant lesions(malignant group).There were statistically significant differences in DCE-MRI parameters,Doppler ultrasound parameters and elastography parameters between the two groups(P<0.05).Binary logistic regression analysis found that enhancement characteristics,morphology,time-signal intensity curve(TIC),blood flow signals on Doppler ultrasound,elastography score,and strain rate(SR)were the influencing factors of benign and malignant breast lesions(P<0.05).The differential diagnostic efficacy of combination of the three examinations was highest.The sensitivity,specificity and accuracy were 88.71%,82.76%and 86.81%,respectively.Conclusion DCE-MRI,Doppler ultrasound,and elastography are effective for differentiating benign and malignant breast lesions.Combination of them can improve the diagnostic performance.
