  3. §ND-CM normal dose contrast medium (320 mgI/kg), LD-CM low dose contrast medium (224 mgI/kg), VMI+ LD-CM images advanced virtual monoenergetic imaging of LD-CM images
  4. P1: the difference between ND-CM images and LD-CM images; P2: the difference between ND-CM images and VMI+ LD-CM images; P3: the difference between LD-CM images and VMI+ LD-CM images by using the Friedman test. p < 0.05 is considered statistically significant
  5. The visualization of the abdominal artery, celiac 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, 3 = completely visible
