title: MRI manifestations of pancreatic disease, especially pancreatitis, in the pediatric population.
abstract: OBJECTIVE
  Although pancreatitis is an uncommon entity in children, the pediatric population can develop serious and long-lasting complications, including pseudocyst, necrosis, hemorrhage, vascular thrombosis, vascular pseudoaneurysm, abscess, and pancreaticopleural fistula. CT has historically been the mainstay for noninvasive imaging of the pancreas. This modality is limited in the pediatric population because of poorly developed retroperitoneal fat planes, difficulty in evaluating the ductal anatomy, and the use of ionizing radiation. MRI with MRCP provides superior soft-tissue resolution and improved visualization of ductal anatomy and can delineate complications of pancreatitis, while avoiding exposure to potentially harmful radiation.
  
  
  CONCLUSIONS
  For these reasons, we advocate abdominal MRI with MRCP as the preferred modality for pancreatic evaluation in the pediatric population. The purpose of this article is to briefly discuss the normal anatomy and embryologic development of the pancreas, review standard sequences for routine abdominal MRI and MRCP in pediatric patients, discuss the normal appearance of the pancreas and biliary tree on MRI sequences, and use examples to illustrate the MRI appearance of common and uncommon manifestations of pancreatic disease in pediatric patients.
