Characteristics of Pediatric Pancreatitis on Magnetic Resonance Cholangiopancreatography.

Hwang JY, Yoon HK, Kim KM - Pediatr Gastroenterol Hepatol Nutr (2015)

Bottom Line: Pediatric pancreatitis is not uncommon and results in considerable morbidity and mortality in the affected children.Unlike adults, pediatric pancreatitis is more frequently associated with underlying structural abnormalities, trauma, and drugs rather than an idiopathic etiology.This article focuses on MRCP findings associated with various causes of pancreatitis in children, particularly structural abnormalities of the pancreaticobiliary system, as well as describing the feasibility, limitations, and solutions associated with pediatric MRCP.

ABSTRACT
Pediatric pancreatitis is not uncommon and results in considerable morbidity and mortality in the affected children. Unlike adults, pediatric pancreatitis is more frequently associated with underlying structural abnormalities, trauma, and drugs rather than an idiopathic etiology. Magnetic resonance cholangiopancreatography (MRCP) is a good imaging modality for evaluating pancreatitis and determining etiology without exposure to radiation. This article focuses on MRCP findings associated with various causes of pancreatitis in children, particularly structural abnormalities of the pancreaticobiliary system, as well as describing the feasibility, limitations, and solutions associated with pediatric MRCP.

Mentions: Respiratory motion artifacts are the most frequent cause of inadequate MRCP imaging, resulting in blurring and ghosting (Fig. 13) [283233]. This motion can result in inconsistent image quality because certain structures cannot be properly found in each sampled k-space, which can cause misdiagnosis because the normal pancreatic duct appears disconnected, stenotic, or dilated [34]. Respiratory motion artifacts can be minimized using the respiratory triggering technique. However, respiratory triggering lengthens the total scan time, especially in patients with irregular respiration due to respiratory misregistration. Moreover, averaging up to six excitations can reduce motion artifacts, although this also increases the scanning time.
