Core Tip

Core Tip: Computed tomography (CT) plays an important role in the diagnosis, staging and treatment of pancreatic tumours. Pancreatic cancer generally shows a low enhancement pattern compared with normal pancreatic tissue. In our analysis, the prognosis of patients with the tumour relative enhancement ratio (TRER) less than or equal to 0.7 was significantly worse than that of patients with TRER greater than 0.7. TRER was significantly correlated with American Joint Committee on Cancer stage, tumour stage, and lymph node stage. Preoperative enhanced CT provides a simple and effective prediction of postoperative overall survival in pancreatic ductal adenocarcinoma.
