Abstract:
Objective To study the relationship of X-ray and MRI features of breast benign lesions with histopathology.Methods The X-ray and MRI features of breast benign lesions in 48 cases were analyzed retrospectively and compared to the histopathogic results.Results There were 18 cases with fibroadenoma and 12 cases with mammoplasia,8 cases with breast galactocele,8 cases with adenosis of breast accompanied by chronic inflammation and 2 cases with lipoma.The structure and vessels of breast were normal mostly in breast benign lesions.The margins of the lesions were clear and the density of lesions was uniformity.The calcifications inside the lesions appeared as granular with definite and smooth margins,less in amounts,growth as plexus-like or diffusive.The lesions were circular,oval or patchy shadows and homogeneous iso-or hypo-intensity on T1WI,iso-or slight hyperintensity on T2WI,and obviously homogeneous enhanced in 4 cases after administration of contrast medium.Conclusion Mammography is the first choice for the breast benign lesions,while MRI can improve the diagnostic accurate rate.
