Abstract:
Objective To evaluate the differential diagnostic value of dynamic contrast enhanced magnetic resonance imaging(DCE-MRI) and diffusion weighted imaging(DWI) in adenosis of the breast and breast cancer.Methods 30 cases of adenosis and 45 cases of breast cancer with pathological verification were scanned with DCE-MRI and DWI.The MRI features of the lesions were analyzed, including shape,margin,T2WI singal, features of enhancement, time intensity curve(TIC) type, early enhancement rate(EER),peak time, background enhancement and ADC value.Results The irregular margin with or without spiculation and the heterogeneous enhancement were mostly seen in breast cancer (P=0.002,P=0.009, respectively).The TIC type Ⅲ, EER larger than 100% and peak time within 2 minutes were mostly seen in breast cancer(P<0.001).The ADC of breast cancer and adenosis were (1.03±0.24)×10-3mm2/s and (1.34±0.30)×10-3mm2/s respectively(P<0.001).The features of shape,T2WI singal and background enhancement had no statistical significance between adenosis and cancer(P>0.05).Conclusion DCE-MRI combined with DWI will be helpful to the diagnosis of breast lesions.
