Abstract
Aim: To investigate the differential diagnostic value of dynamic contrast -enhanced MRI(DCE-MRI) and diffusion weighed imaging (DWI) in benign and malignant breast lesions .Methods:A total of 85 patients with breast tumors underwent DCE-MRI and DWI,the value of ADC and semi-quantitative parameters including TIC type ,Tmax,EER, PER,SER,SImax were measured at a workstation .Differences in these parameters between the benign and malignant groups were compared.Results: There were 62 benign and 34 malignant tumors.The Tmax,PER,SImax,and ADC values of be-nign tumors were significantly higher than malignant tumors (P <0.05),while the SER value of benign tumors were signifi -cantly lower than malignant tumors (P <0.05).There was no statistical difference in EER between benign tumors and ma -lignant tumors(P =0.869).The TIC curves of benign tumors were mostly type Ⅰ(41 /62),and the TIC curves of malignant tumors were mostly typeⅡand typeⅢ(27 /34).The ADC value had the highest diagnostic efficiency (AUC =0.898).Con-clusion: DCE-MRI combined with DWI are of significant value in the differential diagnosis of breast lesions .关键词
