RESUMEN
Objective To evaluate the value of M RI in the diagnosis of breast sclerosing adenosis.Methods 20 cases of breast sclerosing adenosis were analyzed retrospectively.MRI(T1WI,T2WI fat suppression),diffusion-weighted imaging(DWI)and dynamic contrast-enhanced scan were examined.The images were processed by ADW workstation.Apparent diffusion coefficient (ADC),time-signal intensity curve(TIC),maximum intensity projection(MIP)and plain MR features of the breast sclerosing adenosis were analyzed.Results All 20 cases showed iso-or low-intensity on T1WI and heterogeneous high-intensity on T2WI fat suppression.Among 20 cases,the ADC value were between(1.45-1.60)×10-3mm2/s in 12 cases,(1.25-1.45)×10-3mm2/s in 7 cases,(1.00-1.25)× 10-3mm2/s in 1 case.TIC curves were type Ⅰ in 18 cases,type Ⅱ in 2 cases and no case was type Ⅲ.Mass-like lesions were showed in 18 cases which displayed clearly on MIP image.Conclusion Combination of MRI,DWI,dynamic contrast-enhanced can greatly improve the diagnosis accuracy of breast sclerosing adenosis,to provide a reliable basis for clinical treatment.
