摘　　要：目的探讨乳腺良性病变的钼靶X线、MRI表现与病理结果的关系。方法回顾性分析48例乳腺良性病变的钼靶X线、MRI表现特征,并与病理结果对比研究。结果48例中乳腺纤维腺瘤18例,乳腺增生症12例,双乳多发囊肿8例,乳腺腺病伴慢性炎症8例,2例脂肪瘤。乳腺良性病变乳腺结构及局部血管多正常,边缘清晰而光滑,密度均匀。钙化点形态较规则,边缘光滑,颗粒稍大,清晰,数量少,可成簇生长,也可弥散在腺体的一个区内。MRI T1WI表现多为边缘光滑的圆形、卵圆形或片状均匀等或低异常信号,T2WI等或稍高信号。4例增强扫描病变呈明显均一强化。结论乳腺钼靶摄影是乳腺良性病变检查的首选方法,而磁共振成像可提高诊断准确率。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. Resuits 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.
