Abstract:
Objective To evaluate the diagnostic efficiency of multi-parameter magnetic resonance imaging of routine MRI,including dynamic contrast-enhanced MRI(DCE-MRI)and diffusion weighed imaging(DWI)in diagnosis of breast cancer.Methods The results of routine MRI (morphology,boundary and,edge and Internal enhancement),DCE-MRI (1,2,3 minutes early enhanced rate and TIC curve)and DWI (b=500,800 s/mm2 )were analyzed in 43 cases of malignant breast lesions and 54 benign lesions,with pathology results asthe gold standard,the sensitivity,specificity,accuracy,positive predictive value,negative predictive value and Kappa value had been respectively gained,and Logistic regression analysis were used for statistical analysis.Results The specificity of edge (burr sign) was 96.3%,the sensitivity and specificity of TIC curve,ADC values (b=500,800 s/mm2 )were respectively 97.67%,83.33%,81.4%, 90.74%,88.37%,92.59%.Edge (burr sign)and ADC values (b=800 s/mm2 )had a statistic difference in the diagnosis of benign and malignant lesions (P<0.05),TIC curve had a significant statistic difference (P<0.01).Conclusion Edge (burr sign),TIC curve,ADC values (b=800 s/mm2 )had excellent diagnostic efficiency in the diagnosis of benign and malignant lesions.
