Fig. 5From: 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 parametersCalibration curves of DECT–Radiology nomogram in cohorts of training and validation (a, b). Diagonal implies DECT–Radiology nomogram of an ideal performance. Closer to the diagonal implies more accuracy. DECT, dual-energy computed tomographyBack to article page
