ROIs drawn to compute the time-enhancement curves. In A, a ROI on the pancreas was drawn on the largest pancreatic portion included in the CT study volume. While this portion is usually represented by the pancreatic head, in this case the pancreatic head was not included in the study volume due to a pathologic lymph node and the ROI was drawn on the pancreatic tail. B ROI drawn on an HCC focus. C ROI drawn on the cortex of the right kidney. D ROI drawn in the aorta, between the emergency of the superior mesenteric artery and of the renal arteries
