Fig. 6 — RSDECT scan, pancreatic parenchymal phase of patient with pancreatic head ductal adenocarcinoma (white arrow) as seen on A)70keV monochromatic B) true precontrast, C) water-iodine or water(-iodine), and D) material suppressed iodine (MSI). The water(-iodine) yields measurements in calculated density, while an ROI on the MSI image would provide calculated Hounsfield units. Note the appearance of the renal cortex on the virtual noncontrast images versus the true precontrast image. A metallic common bile duct stent is present within the pancreatic head (white arrowhead)
