Diffusion-weighted imaging of biliopancreatic disorders: Correlation with conventional magnetic resonance imaging

Figure 6 Acute pancreatitis and cholecystitis due to a bile duct stone in a 72-year-old woman. A: Axial T2-weighted rapid acquisition relaxation enhancement image demonstrates stones in the distal common bile duct (arrow), a distended gallbladder with pericholecystic fluid, and pancreatic edema with peripancreatic fluid, findings suggestive of cholecystitis and pancreatitis; B: DWI at b = 800 s/mm² shows that the pancreas is slightly hyperintense (asterisk) compared to the liver, and the presence of a peripancreatic fluid collection; findings indicative of pancreatitis. A distended gallbladder with diffuse and symmetric high signal intensity in the wall (arrowheads), due to the restriction of water diffusion in the inflamed gallbladder wall, is also seen. DWI: Diffusion-weighted magnetic resonance imaging.
