Figure 3. 34-year-old woman with chronic pancreatitis after injection of Iomeprol 400: (a) arterial phase, (b) portal venous phase. Figure 3a demonstrates the higher arterial phase contrast enhancement of the spleen with Iomeprol 400 compared with Iomeprol 300 (Figures 2e and f). Figure 3b shows the higher portal venous phase contrast enhancement for the portal vein with Iomeprol 400 compared with Iomeprol 300 (Figures 2g and h).
