Artifacts are universal across all imaging modalities, varying in their conspicuity and significance. In this report three patients with pathology-proven breast cancer who had densities masquerading as microcalcifications at the resection margins of the lumpectomy specimens, but had negative microscopic margins, will be discussed. It was determined that these pseudocalcifications were the result of ink precipitates from a commonly utilized tissue marking dye. This artifact was further evaluated and reproduced by utilizing a boneless chicken breast as a phantom. RSNA, 2016.
伪影在所有影像学模态中都普遍存在，其显著性和意义各不相同。本报告讨论了三例经病理证实患有乳腺癌的患者，这些患者的肿瘤在保乳手术标本的切缘有密度表现为微钙化的情况，但显微镜下切缘为阴性。确定这些假钙化是一种常用的组织标记染料的墨淀所致。为了进一步评估和再现这种伪影，我们使用去骨鸡胸作为模型进行了实验。RSNA，2016。
