Hepatic abnormal perfusion visible by magnetic resonance imaging in acute pancreatitis

Figure 1 A 65-year-old man with acute pancreatitis combined with cholecystitis as well as common bile duct and intrahepatic bile duct dilatation. Fast recovery fast spin-echo T2-weighted image (A) shows gallbladder distention (arrowhead), perigallbladder fluid (short arrow), common bile duct dilatation (short arrow), and peripancreatic strand hyperintensity signal (long arrow). Patch- or wedge-shaped hepatic abnormal perfusion is found in the left and right lobes of the liver on the artery phase images (B, arrow) and returns to normal on the venous phase images (C).

Figure 2 A 43-year-old woman with acute pancreatitis combined with cholecystitis. Respiratory-triggered axial fast recovery fast spin-echo T2-weighted image (A) shows the peripancreatic strand hyperintense signal and perinephric fluid collection (short arrow) as well as perigallbladder fluid (long arrow). Strip-shaped hepatic abnormal perfusion is found in the hepatic tissue adjacent to the gallbladder on the arterial phase images (B, arrow) and returns to normal on the venous phase images (C).

Figure 3 A 49-year-old man with acute pancreatitis combined with cholecystitis, gallbladder stone and common bile duct dilatation. Respiratory-triggered axial fast recovery fast spin-echo T2-weighted image (A) shows cholecystitis and gallbladder stones (short arrow) as well as common bile duct dilatation (long arrow). Patch- or wedge-shaped hepatic abnormal perfusion is found in the left lobe of the liver on arterial phase images (B, arrow).

Figure 4 A 50-year-old woman with acute pancreatitis without gallbladder and common bile duct abnormalities. Fast recovery fast spin-echo T2-weighted image (A) shows peri-pancreatic strand hyperintensity signal (arrow). Wedge-shaped hepatic abnormal perfusion (arrow) is found in the right lobe of liver on the artery phase (B) and returns to normal on the venous phase images (C).

Figure 5 A 45-year-old man with acute pancreatitis without gallbladder or common bile duct abnormalities. Fast recovery fast spin-echo T2-weighted image (A) shows the left anterior pararenal space fluid collection (arrow). Wedge-shaped hepatic abnormal perfusion (arrow) is found in the left inner lobe of the liver on the arterial phase (B) and venous phase images (C).
