Fig. 4From: The differentiation of pancreatic neuroendocrine carcinoma from pancreatic ductal adenocarcinoma: the values of CT imaging features and texture analysisReceiver operating characteristic curves of the contrast ratio at the arterial phase (AER) and portal phase (PER) (A), and texture parameters (uniformity, uni; entropy, ent) (B) at portal phase for differentiating pancreatic neuroendocrine carcinoma (PNEC) from pancreatic ductal adenocarcinoma (PDAC). Entropy and uniformity at high sigma values had acceptable AUCs (> 0.70)Back to article page
