Magnetic resonance cholangiopancreatography (MRCP) is a
biliary and pancreatic ducts non-invasively. This procedure can be used to determine whether gallstones are lodged in any of the ducts surrounding the gallbladder
.
Uses
MRCP has been slowly replacing
biliary system, pancreatic duct and accessing surrounding solid organs. Several advantages offered by MRCP is its non-invasive nature, less costly, requires less examination time when compared to ERCP (30 minutes), fewer staff required, and does not require any ionising radiation.[1][2][3][4]
MRCP is used to diagnose
liver cirrhosis and cholangiocarcinoma.[5]
Technique
Subject is needed to fast for at least four hours to ensure the biliary system is maximally distended with fluid while keeping the fluid in the gastrointestinal system at a minimum.Açaí juice and water are useful in decreasing T2 signal intensity, thus minimising signals from stomach and duodenum from interfering with signals from the biliary system.[6]
MRCP makes use of heavily
T2-weighted MRI pulse sequences.[3][7] These sequences show high signal in static or slow moving fluids within the gallbladder, biliary ducts and pancreatic duct, with low signal of surrounding tissue. Secretin is also given to a patient to increase ductal compliance, making imaging easier.[3]
History
It was introduced by Wallner in 1991.[8]
