Breast cancer is the most common cancer in women; approximately 1 in 8 women is diagnosed with breast cancer in their lifetime. Some women are at significantly higher risk of developing breast cancer, including women carrying mutations in the BRCA1/2, TP53, or other genes and women with other risk factors. Women with a high lifetime risk for breast cancer are frequently offered annual breast magnetic resonance imaging (MRI) examinations for early breast cancer detection. Breast MRI is commonly performed using a multiparametric imaging protocol, including dynamic contrast-enhanced T1-weighted acquisitions. The dynamic contrast-enhanced T1-weighted acquisitions are frequently transformed into subtraction series, allowing the focused visualization of areas with high signal intensity and masses associated with elevated contrast agent uptake, which are among the hallmarks of suspicious findings. Here, we report a case in which a suspicious lesion-mimicking swap artifact occurred using a T1-weighted contrast-enhanced DIXON acquisition technique in a high-risk breast cancer screening MRI examination.
乳腺癌是女性中最常见的癌症；大约每8名女性中就有1人在其一生中被诊断出患有乳腺癌。一些女性患乳腺癌的风险显著更高，包括携带BRCA1/2、TP53或其他基因突变的女性以及有其他风险因素的女性。乳腺癌终生风险高的女性经常接受每年一次的乳房磁共振成像（MRI）检查以早期发现乳腺癌。乳房MRI通常使用多参数成像协议进行，包括动态对比增强T1加权采集。动态对比增强T1加权采集经常被转换为减影序列，从而能够聚焦显示高信号强度区域以及与造影剂摄取增加相关的肿块，这些都是可疑发现的特征。在此，我们报告一例在高危乳腺癌筛查MRI检查中，使用T1加权对比增强DIXON采集技术出现类似可疑病变的交换伪影的病例。
