Histograms of the subjective scores of artery depiction in ND-CM, LD-CM, and VMI+ LD-CM images. Histograms show the subjective scores of the abdominal aorta, its main branches, and pancreatic arteries in ND-CM (0.8 mL/kg, 400 mgI/mL, and 320 mgI/kg), LD-CM (0.56 mL/kg, 400 mgI/mL, and 224 mgI/kg), and VMI+ LD-CM images. Visualization of the abdominal artery, celiac artery, and superior mesenteric artery (SMA) were graded using a 4-point scale: 1 = no depiction, 2 = faint depiction, 3 = good depiction, and 4 = excellent depiction. The depiction of pancreatic arteries was graded using a 4-point scale: 0 = not visible, 1 = partially visible, 2 = partially invisible or slightly irregular appearance, and 3 = completely visible. ND-CM normal-dose contrast medium, LD-CM low-dose contrast medium, VMI+ advanced virtual monoenergetic imaging
