Figure 8. Acute necrotizing pancreatitis demonstrated on MRCP (A) and coronal thin-section single-shot TSE T2-weighted (B) images. In A, a distal common bile duct stricture (arrow), abnormal pancreatic duct side branches (solid arrowheads) and indirect signs of duodenal wall thickening (open arrowheads) are visualized. The peripancreatic fluid collections detected in B (arrows) are not detected in A, because of the shorter T2 relaxation time of the fluid in the peripancreatic collections. However, because of intrinsic limitations in signal-to-noise ratio and spatial resolution, this sequence is not useful for detection of solid lesions within the pancreas or the liver (Fig 9)
