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.

A 16-year-old boy diagnosed with chronic pancreatitis. (A) This single-shot radial acquisition with relaxation enhancement magnetic resonance cholangiopancreatography image fails to show the pancreatic duct. (B) The pancreatic duct was well visualized 4 minutes after the administration of secretin (arrow).

Figure 14: A 16-year-old boy diagnosed with chronic pancreatitis. (A) This single-shot radial acquisition with relaxation enhancement magnetic resonance cholangiopancreatography image fails to show the pancreatic duct. (B) The pancreatic duct was well visualized 4 minutes after the administration of secretin (arrow).

Mentions: Neonates and young infants have small bile ducts that measure approximately ≤1 mm in diameter, and the pancreatic duct is even smaller than the bile duct in normal patients. Such small structures produce fewer signals and tend to be more susceptible to respiratory motion artifacts. These problems could be solved using strategies that improve the SNR and reduce motion artifacts. In addition, secretin-stimulated MRCP can improve visualization of the pancreatic duct by triggering transient dilatation (Fig. 14) [10323637].
