Magnetic resonance cholangiopancreatography (MRCP) is a medical imaging technique. It uses magnetic resonance imaging to visualize the 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 is used to visualize the biliary and pancreatic ducts in a non-invasive manner.[1][2] It is used to diagnose gallstones. It can also diagnose choledochal cysts very reliably.[3] This is useful for visualisation, making other surgeries easier.[3]

Technique[]

MRCP makes use of heavily T2-weighted MRI pulse sequences.[2][4] 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.[2]

Comparison to other techniques[]

In the diagnosis of pancreatic disorders, MRCP is a much less invasive investigation when compared to endoscopic retrograde cholangiopancreatography (ERCP). Although both techniques can image the ductal system in detail, MRCP also allows imaging of the surrounding parenchyma. In a study from 2008, 269 patients undergoing both ERCP and MRCP showed comparable results between the two techniques.[5]

History[]

It was introduced by Wallner in 1991.[6]
