MRCP and MRI findings in 9 patients with autoimmune pancreatitis

Figure 1 A: On MRCP of a patient with autoimmune pancreatitis, 2 segmentally skipped lesions of the main pancreatic duct in the head and body of the pancreas were not visualized; B: After steroid therapy, the entire MPD was seen on MRCP.

Figure 2 A: On T1-weighted MR images of a patient with autoimmune pancreatitis, the signal intensity of the affected pancreatic lesion was slightly decreased compared to the signal intensity in the liver; B: T2-weighted MR images showed increased signal intensity in the pancreatic parenchyma than that of the liver with a capsule-like rim which was hypointense; C: After steroid therapy, the enlarged pancreas became atrophic on T1-weighted MR images.
