摘要
目的探讨乳腺良性病变的病理结果与MRI表现的关系,总结乳腺良性病变的MRI特征。方法回顾性分析31例乳腺良性病变的乳腺MRI表现,并与病理结果对比分析。结果31例患者中,单纯乳腺腺病8例;在乳腺腺病基础上合并其他乳腺良性病变12例;乳腺导管扩张3例;乳腺纤维腺瘤3例;乳腺导管内乳头状瘤5例。乳腺良性病变乳腺结构多正常,MRI表现多为边缘光滑的圆形、卵圆形或片状信号异常,T1WI等或低异常信号,T2W I等或稍高信号。动态增强时间-信号强度曲线中,良性病变以I型曲线为主。结论乳腺良性病变的MRI表现与病变病理结构密切相关,正确认识良性病变的特征性MRI表现有助于鉴别诊断。
Objective To investigate the relationship between MRI features and pathological features of breast benign lesions. Methods MRI features of breast benign lesions in 31 cases were retrospectively analyzed and compared to the histopathogic results. Resuits There were 8 cases with adenosis of breast, 12 cases with other breast benign lesions by adenosis of breast, 3 cases with mammary duct ectasia, 3 cases with fibroadenoma and 5 cases with intraductal papilloma of the breast. The structure of breast was normal in breast benign lesions. The lesions were circular, oval or patchy shadows and homogeneous iso -or hypo -intensity on T1WI, iso -or slight hyperintensity on T2WI, For the time - signal intensity curve, most of benign diseases were type Ⅰ. Conclusion MRI features of breast benign lesions are correlated with pathological features, familiarity with the diagnostic features would make the differential diagnosis correctly.
