MRCP
Pronunciation: M-R-C-P
Also written as: MRCP — magnetic resonance cholangiopancreatography
Non-invasive imaging technique used to visualize the biliary and pancreatic ductal systems.
Full Definition
Magnetic resonance cholangiopancreatography (MRCP) is a specialized MRI technique that provides detailed images of the biliary tree and pancreatic ducts without the need for contrast injection or invasive procedures. In pediatric gastroenterology, MRCP is particularly valuable for evaluating suspected biliary abnormalities, pancreatic disorders, and choledochal cysts. The technique uses heavily T2-weighted sequences that highlight fluid-filled structures, making bile ducts and pancreatic ducts appear bright against darker surrounding tissues. MRCP has largely replaced diagnostic ERCP in children due to its non-invasive nature and lack of radiation exposure.
Usage
Usage note: Always capitalize acronym; distinguish from ERCP in clinical documentation.
