An MRI Abdomen (MRCP – Magnetic Resonance Cholangiopancreatography) is a specialized type of abdominal MRI that creates detailed images of the gallbladder, bile ducts (the tubes that carry bile from the liver to the intestine), and the pancreatic duct (the tube that drains digestive enzymes from the pancreas). Many people also search for this test as a MRCP, bile duct MRI, gallbladder MRI, or pancreatic duct scan.

MRCP uses MRI technology (a strong magnet and radio waves) to highlight fluid-filled structures like bile and pancreatic juice. This makes it especially good at spotting problems such as gallstones in the bile duct, narrowing (strictures), blockages, inflammation, and certain biliary or pancreatic tumors. Unlike ERCP (endoscopic retrograde cholangiopancreatography), MRCP is noninvasive—no endoscope is passed into the stomach or bile duct.

Your results are usually reported as normal (bile ducts and pancreatic duct are normal in size and shape with no blockage) or abnormal. Abnormal findings may include dilated ducts (often suggesting a blockage), a visible stone, a tight narrowing (stricture), signs of infection/inflammation, or a mass that needs further evaluation. Your clinician will interpret the MRI/MRCP findings together with symptoms, blood tests (such as liver function tests), and other imaging to determine the cause and next steps.

Doctors commonly order an abdominal MRI with MRCP when they need a clear, detailed look at the biliary system and pancreatic duct—especially when symptoms or lab results suggest a blockage or disease affecting bile flow or the pancreas.

This test may be recommended if you have:

Symptoms that suggest a bile duct or gallbladder problem, such as:

• Pain in the upper right or upper middle abdomen (especially after fatty meals)
• Yellowing of the skin/eyes (jaundice)
• Dark urine, pale stools, or generalized itching (possible bile flow blockage)
• Nausea/vomiting, fever, or chills (possible infection such as cholangitis)

Symptoms that suggest a pancreas or pancreatic duct issue, such as:

• Severe upper abdominal pain that may radiate to the back
• Recurrent or unexplained pancreatitis
• Unintended weight loss or loss of appetite (may require evaluation for obstruction or mass)

Abnormal blood tests that raise concern for bile duct blockage or liver/pancreas irritation, including elevated bilirubin, alkaline phosphatase, GGT, AST/ALT, or pancreatic enzymes (amylase/lipase).

Follow-up of prior imaging (ultrasound or CT) when results are unclear or when more detail is needed to map the ducts before treatment. MRCP can also help plan next steps—such as whether an ERCP is needed to remove a stone or place a stent.

Evaluation of known conditions, such as primary sclerosing cholangitis (PSC), suspected bile duct stricture after surgery, or congenital duct abnormalities.

• Choledocholithiasis (gallstones in the common bile duct)
• Gallbladder disease, including gallstones and cholecystitis (gallbladder inflammation)
• Biliary obstruction (blocked bile ducts)
• Bile duct strictures (benign narrowing, including post-surgical strictures)
• Cholangitis (infection/inflammation of the bile ducts)
• Primary sclerosing cholangitis (PSC)
• Pancreatitis (acute or chronic), including evaluation of pancreatic duct changes
• Pancreatic duct obstruction or stricture
• Pancreatic cysts (e.g., IPMN) and other cystic pancreatic lesions
• Cholangiocarcinoma (bile duct cancer)
• Pancreatic cancer or periampullary tumors causing duct blockage

• Identifying the cause of jaundice and improving bile flow by guiding appropriate treatment
• Diagnosing and preventing complications from gallstones (including stones that move into the bile duct)
• Evaluating recurrent abdominal pain by ruling in or out bile duct or pancreatic duct problems
• Reducing risk of recurrent pancreatitis by detecting pancreatic duct blockage, narrowing, or structural abnormalities
• Monitoring chronic biliary conditions (such as PSC) and assessing disease progression
• Clarifying abnormal liver function tests by checking for biliary obstruction or stricture
• Supporting early detection and workup of suspected biliary or pancreatic tumors when symptoms or imaging raise concern
• Planning next steps before procedures (e.g., deciding whether ERCP or surgery is needed and mapping duct anatomy)
