目的：本研究的目的是确定磁共振成像（MRI）的功能与再切除由于存在一个积极的边缘后保乳治疗（BCT）在乳腺癌patients.Materials和方法：我们回顾了286例连续乳腺癌患者谁收到BCT在2006年1月至2007年12月的记录。在246例接受BCT的患者中，38例（15.4%）因切缘阳性而立即再次手术。采用χ2检验、Fisher精确检验和t检验对MRI表现进行分析，并进行多因素Logistic回归分析。结果：肿瘤大小（p < 0.001）、病变多样性（p = 0.003）和MRI上非肿块样强化（NMLE）类型（p <0.001）是影响再次切除的主要因素。
Purpose : The aim of this study was to determine the magnetic resonance imaging (MRI) features associated with re-excisiondue to the presence of a positive margin after breast conserving therapy (BCT) in breast cancer patients.Materials and Methods: We reviewed the records of 286 consecutive breast cancer patients who received BCT betweenJanuary 2006 and December 2007. Among 246 patients who had undergone BCT, 38 (15.4%) underwent immediatefurther surgery due to positive margin status. We analyzed the MRI findings using χ2 test, Fisher’s exact test and t tests.Multivariate logistic regression was conducted for prediction of re-excision.Results: Tumor size (p < 0.001), lesion multiplicity (p = 0.003), and non-mass-like enhancement (NMLE) type on MRI (p
