【摘要】 目的 探讨乳腺纤维囊性增生病(FBD)的磁共振成像(MRI)特征性表现。方法 对39例经术后病理证实为FBD的病例进行回顾性分析。成像序列包括增强前和动态增强扫描双侧乳房乳腺评估容积成像(VIBRANT)技术。病变根据乳腺影像报告和数据系统(ACR BI-RADS-MRI Lexicon)中形态学和增强动力学描述语来描述其MRI特征表现。结果 本组FBD MR动态增强表现为3种类型,13例实性结节,多数呈恶性病变动力学表现;15例囊肿型无强化或环形轻度强化,其中1例合并左乳导管周围炎病变明显强化并呈速升速降型;6例无肿块型通常呈良性增强动力学表现。5例MR平扫和增强扫描均未见明确异常表现。结论 MRI动态增强扫描对FBD的诊断具有重要价值。更多还原

【Abstract】 Objective To analyze the MRI features of fibrocystic breast disease(FBD).Methods 39 patients with pathologically proven FBD were retrospectively reviewed.The imaging protocol consisted of pre-contrast imagings and bilateral breast volume imaging for breast assessme NT(VIBRANT).MRI features were interpreted based on the morphologic and enhancement kinetic descriptors defined on ACR DIRADS-MRI lexicon.Results There were 3 types on ACR BI-RADS-MRI lexicon in FBD,including13 focal mass-type showing malignant enhancement kinetic pattern mostly;15 cyst-type with non-enhancement or mild enhancement,of them,1 case with periductal mastitis showing strong enhancement and rapid up-slope and wash-out mimicking a breast cancer.6 non-mass type usually showing benign enhancement kinetic pattern.In 5 patients, MRI did not show definite abnormal evidence.Conclusion MRI is of significant value in diagnosing FBD.更多还原
