  1. Data are means ± standard deviations or Median (P25, P75)
  2. *PSPDA posterior superior pancreaticoduodenal artery, ASPDA anterior superior pancreaticoduodenal artery, IPDA inferior pancreaticoduodenal artery, AIPDA anterior inferior pancreaticoduodenal artery, PIPDA posterior inferior pancreaticoduodenal artery, DPA dorsal pancreatic artery, TPA transverse pancreatic artery, GPA great pancreatic artery, CPA caudal pancreatic artery
  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
