Magnetic resonance cholangiopancreatography (MRCP) is a medical imaging technique that uses magnetic resonance imaging to visualise 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

In the diagnosis of biliary and 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 recent study of 269 patients undergoing both ERCP and MRCP, the MRCP compared favourably with the more invasive technique.^[3] As with other forms of Magnetic Resonance imaging, appearances can sometimes be deceptive.^[4]
