目的分析乳腺MRI动态增强上簇环样强化征象的病理基础和鉴别诊断价值。资料与方法回顾性分析经病理证实的105个簇环样强化病灶,与病理对照分析簇环样强化的成分,用Logistic回归分析簇环样强化时间-信号曲线(TIC)类型对鉴别乳腺病灶良恶性的价值。结果以病理与影像测量大小接近为判断依据,簇环样强化与典型的终末导管小叶单位(TDLU)对应,可划分为中心低信号、强化的小环、环周3个部分,中心低信号部分对应扩张的导管或细胞致密的瘤巢,强化的小环对应富血供的导管周围、小叶单位之间和瘤巢周围的基质,环周组织对应包括癌细胞或炎症细胞甚至正常组织。廓清型TIC对恶性病变的诊断有预测价值(OR=30.0,...

Purpose To correlate the clustered ring sign on the multiphase contrast-enhanced breast MRI imaging with its pathological findings and to evaluate its efficacy in predicting malignancy of the breast lesions.Materials and methods One hundred and five lesions presenting clustered ring sign on the contrast-enhanced MR imaging were pathologically confirmed.Their morphological features were head-to-head correlated to the pathological components.The emerging timing and the time-intensity curve(TIC)types were optimized for benign and malignant differentiation using Logistic regression analysis.Result...
