Acute pancreatitis: Structured report template of magnetic resonance imaging

Figure 6 The radiological changes in pancreatic/peripancreatic fluid. A 49-year-old woman with acute necrotizing pancreatitis and pancreatic walled-off necrosis, performed by endoscopic ultrasound drainage. A: Magnetic resonance imaging fat-suppressed T1-weighted imaging shows a walled-off necrosis (WON) with a diameter of 10 cm × 9 cm in the omental sac and pancreatic body and tail, as well as numerous necrotic fragments (arrowheads) within the WON. The WON is adjacent to the gastric body; B: Thereafter, under the guidance of endoscopic ultrasonography, a fully coated mushroom metal stent (arrow) was placed through the stomach for internal drainage; C: Postoperative computed tomography image shows that the WON was apparently decreased, with a large amount of gas and a high-density stent (arrow) in place. St: Stomach, P: Pancreas, GB: Gallbladder.
