MRCP (MR cholangiopancreatography)

MRCP in Tunis, Tunisia · Centre Urbain Nord

MRCP in Tunis: MRI of the bile ducts and pancreatic duct to look for a stone or narrowing, without endoscopy or X-rays.

What is it?

MRCP (MR cholangiopancreatography) is an MRI that shows the ducts carrying bile from the liver to the intestine (bile ducts, including the common bile duct) as well as the pancreatic duct. It relies on MRI's ability to show fluids in white: the bile then appears as if drawn on a map, without injecting anything into the ducts and without endoscopy. It can look for a stone stuck in the common bile duct, or a narrowing or widening of the ducts. It is usually performed without a gadolinium injection and is often combined with an MRI of the liver and pancreas. Fasting is essential so that the gallbladder is well filled and the stomach empty.

When is it indicated?

Suspected stone in the common bile duct

After pain, jaundice or abnormal liver tests, it looks for a stone that has passed from the gallbladder into the bile ducts.

Unexplained jaundice

It shows where and why bile is no longer flowing normally.

Pancreatitis

It looks for a cause (stone, abnormality of the pancreatic duct) and for complications.

Assessment before gallbladder removal or biliary endoscopy

It helps the doctor know whether a procedure on the bile ducts is needed.
