Magnetic resonance cholangiopancreatography (MRCP) is a medical imaging technique that uses magnetic resonance imaging to visualize the biliary and pancreatic ducts in a non-invasive manner.[1] This procedure can be used to determine if gallstones are lodged in any of the ducts surrounding the gallbladder.

It was introduced in 1991.[2]

Comparison to other techniques[edit]

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 that the MRCP compared favourably next to the more invasive technique.[3]
