Diagnostic imaging plays a critical role in the initial diagnosis and therapeutic monitoring of pancreatic adenocarcinoma. Over the past decade, the concept of ‘borderline resectable’ pancreatic cancer has emerged to describe a distinct subset of patients existing along the spectrum from resectable to locally advanced disease for whom a microscopically margin-positive (R1) resection is considered relatively more likely, primarily due to the relationship of the primary tumor with surrounding vasculature.

边界可切除的胰腺癌：概念演变和当前的基于图像的分类方法

诊断成像在胰腺腺癌的初始诊断和治疗监测中起着至关重要的作用。在过去的十年中，“边界可切除”胰腺癌的概念出现了，它描述了从可切除到局部晚期疾病范围内存在的患者的独特子集，对于这些患者，镜下边缘阳性（R1）切除术被认为相对可能性更高，主要是由于原发肿瘤与周围脉管系统的关系。
