Figure 37. Obstructive chronic calcified pancreatitis. (A) MRCP shows characteristic alterations with marked ductal dilatation, filling defects, and a smooth common bile duct stricture (arrowhead). (B, C) Corresponding cross-sectional MR images demonstrate glandular enlargement and decreased signal intensity on the water-stimulated GRE T1-weighted image (arrowheads in C). Extrinsic gastric wall compression (arrows) due to glandular enhancement is also displayed on both MRCP (A) and coronal HASTE T2-weighted (B) images.
