目的:观察乳腺背景实质强化(background parenchymal enhancement,BPE)在不同分子分型的乳腺癌患者中的分布情况,并分析其与乳腺癌分子分型的关系。方法:回顾性分析150例乳腺癌患者的MRI动态增强扫描图像,根据雌激素受体(estrogen receptor,ER)、孕激素受体(progesterone receptor,PR)、人类表皮生长因子受体-2(human epidermal growth factor receptor 2,HER-2)和细胞增殖的相关抗原Ki-67的表达状态,将乳腺癌分为管腔A型(Luminal-A型)、管腔B型(Luminal-B型)、HER-2型和三阴型,并根据乳腺影像报告和数据系统(breast imaging and reporting data system,BI-RADS)标准,将BPE分为4型,即轻微强化、...

Objective: To observe the distribution of magnetic resonance imaging (MRI) breast parenchymal enhancement (BPE) among different breast cancer subtypes and to explore the relationship between the BPE and the breast cancer tumor type. Methods: A total of 150 consecutive patients with breast cancer underwent breast dynamic enhanced scanning image. According to the expression of estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER-2) and Ki-67, the molecular subtypes were classified into Luminal-A, Luminal-B, HER-2 overexpression, and triple-negative br...
