A striking number of patients are diagnosed with resectable pancreatic cancer (PC) or borderline resectable PC by computed tomography (CT) but end up with positive (R1) resection at surgery according to the National Comprehensive Cancer Network (NCCN) criteria. If the pathological resection margin can be accurately and noninvasively predicted prior to surgery, an appropriate treatment plan can be developed and patients with PC can avoid futile surgery. Hence, we sought to accurately identify the relationship between the arterial radiomics score (rad-score) and pathologic superior mesenteric vein (SMV) resection margin in patients with pancreatic head cancer and to evaluate the diagnostic performance of the rad-score in differentiating between negative (R0) and R1 resection.
