From: Development and validation of a model for predicting the expression of Ki-67 in pancreatic ductal adenocarcinoma with radiological features and dual-energy computed tomography quantitative parameters

Fig. 4

DECT–Radiology nomogram was diagramed uniting one radiological and two DECT variables. The points of each predictive index are scored by the corresponding values on “point line”. The total scores are obtained from the summation of the points of all predictive indexes to assess the Ki-67 expression in PDAC. CT, computed tomography; DECT, dual-energy computed tomography; ECVf, the extracellular volume fraction; LN, lymph node; NIC, normalized iodine concentration; PDAC, pancreatic ductal adenocarcinoma; PVP, portal venous phase
