摘要目的通过与ER+/HER2-(ER+)和HER2+乳腺癌对比在动态增强、扩散加权MRI中的表现,明确侵袭性三阴性乳腺癌的MRI特征。方法共269例侵袭性乳腺癌病人、271个病灶纳入研究。由2名影像科医师回顾性分析DCE-MRI上病变的形态学和动态增强扫描特征,以及DWI对肿瘤检出率,并测量各个病灶的ADC值。
Abstract Objective To clarify the MRI features of invasive triple-negative breast cancer by contrasting with ER + / HER2- (ER +) and HER2 + breast cancer in dynamic contrast-enhanced and diffusion-weighted MRI. Methods A total of 269 cases of invasive breast cancer patients, 271 lesions were included in the study. Two imaging physicians retrospectively analyzed the morphological and dynamic contrast-enhanced features of lesions on DCE-MRI, as well as the detection rate of tumors by DWI and the ADC value of each lesion.
