MRCP vs. ERCP

Unlike conventional endoscopic retrograde cholangiopancreatography (ERCP), MRCP does not require contrast material to be administered. Thus, the morbidity associated with endoscopic procedures and contrast materials is avoided. However, MRCP does not currently allow any intervention to be performed, such as stone extraction, stent insertion, or biopsy.

As the specificity of this non-invasive technique is close to 100%, MRCP may prevent inappropriate invasive explorations of the common bile duct and pancreatic duct.

Poor Inter-Reader Reliability of Magnetic Resonance Cholangiopancreatography in Primary Sclerosing Cholangitis

PSC remains a challenge to evaluate and treat. Many gastroenterologists rely on MRCP interpretations when deciding whether to perform ERCP procedures in patients with PSC. Although small, this study does serve as a cautionary tale, given the poor inter-reader agreement demonstrated by the authors. In my own experience, MRCP reports often do not match the findings seen on ERCP (which produces a gold-standard cholangiogram, albeit with increased invasiveness and risks to the patient).

The diagnostic MRCP examination: overcoming technical challenges to ensure clinical success

The magnetic resonance cholangiopancreatography (MRCP) examination has all but replaced the diagnostic endoscopic retrograde cholangiopancreatography (ERCP) examination for imaging the biliary tree and pancreatic ducts in many practical aspects of the clinical setting.

Value of magnetic resonance cholangiopancreatography prior to endoscopic retrograde cholangiopancreatography in ultrasonographically and laboratory diagnosed obstructive jaundice

This study showed that MRCP before ERCP is very beneficial, decreases considerably the number of unnecessary ERCP, and decreases postoperative complications of ERCP.

CTCA

Doctors use MRCP scans as noninvasive alternatives to ERCP scans. These scans provide information on diseases and conditions affecting the liver, gallbladder, bile ducts, pancreatic ducts and pancreas—including bile duct cancer (cholangiocarcinoma) and pancreatic cancer, infection, inflammation (pain, heat, redness, swelling and loss of function), and gallstones and bile duct stones.

Magnetic resonance cholangiopancreatography: the ABC of MRCP

It has now an established role in the investigation of many biliary disorders, serving as a non-invasive alternative to endoscopic retrograde cholangiopancreatography (ERCP).

RadiologyInfo.org

MRCP can produce images comparable to those obtained by a more invasive exam called endoscopic retrograde cholangiopancreatography (ERCP) without its associated risks including pancreatitis, or inflammation of the pancreas, perforation of pancreatic and bile ducts and bowel, and the risks for intravenous sedation required for ERCP.

Radiopaedia

The technique exploits the fluid which is present in the biliary and pancreatic ducts as an intrinsic contrast medium by acquiring the images using heavily T2-weighted sequences.
