乳腺背景实质强化的MRI研究进展

Research progresses of breast background parenchymal enhancement of MRI

乳腺背景实质强化(BPE)是乳腺动态增强MRI所特有的一种表现形式,在乳腺疾病诊断中的作用以及BPE与乳腺癌患病风险、预后等的关系已成为研究的热点。本文对乳腺背景实质强化的定义及典型表现、BPE对MRI诊断的影响、BPE的影响因素、BPE与乳腺纤维腺体组织含量的关系以及BPE与乳腺癌发病风险的相关性等进行综述。

Breast background parenchymal enhancement（BPE）is a special form of breast dynamic contrast enhanced MRI.The diagnosis and research of breast diseases which shows BPE is becoming more and more important.The relationship between BPE and the risk factors of breast cancer is one of the focuses in breast MRI.In this review,the definition and typical manifestations of BPE,the relationship between BPE and fibroglandular tissue,and the influence factors of BPE in the breast MRI were reviewed.
