Acute pancreatitis: Structured report template of magnetic resonance imaging

Figure 1 Pancreatic and peripancreatic necrosis. A: Schematic diagram of pancreatic and peripancreatic necrosis (mixed type): pancreatic body necrosis (N) accompanied by peripancreatic fatty tissue debris (FD); B: A 61-year-old male with acute necrotizing pancreatitis (both pancreatic and peripancreatic necrosis). Fat-suppressed axial T1-weighted imaging shows a wide range of necrosis of the head and body of the pancreas (arrowheads), as well as peripancreatic collections containing large amounts of fat necrotic debris (arrows); C: Schematic diagram of necrotizing pancreatitis (peripancreatic necrosis alone): FD and absence of necrosis of pancreatic parenchyma; D: A 65-year-old woman with acute necrotizing pancreatitis (peripancreatic necrosis alone). Magnetic resonance imaging T2WI shows multiple patchy fatty fragments (hypointensity areas) (arrows) surrounding the pancreas.
