Abstract:
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 elastogra-phy 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 regres-sion 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.
