Magnetic resonance cholangiopancreatography (MRCP) is a medical imaging technique. It uses magnetic resonance imaging to visualize the biliary and pancreatic ducts non-invasively. This procedure can be used to determine whether gallstones are lodged in any of the ducts surrounding the gallbladder .
Computed Tomography: Non-contrast and contrast-enhanced CT may demonstrate dilation of both ducts and identify an underlying mass in the pancreas or ampulla, if present. Magnetic Resonance Cholangiopancreatography (MRCP): Non-invasive procedure, that clearly shows dilated CBD and MPD and may help pinpoint the obstruction site.
MRCP may be: Magnetic resonance cholangiopancreatography , in medical imaging, a technique to visualise the biliary tract and pancreatic ducts. Membership of the Royal Colleges of Physicians of the United Kingdom , a postgraduate medical diploma run by the Federation of the Medical Royal Colleges of the United Kingdom
Extracellular contrast agents are used widely in liver MRI, and newer hepatobiliary contrast agents also provide the opportunity to perform functional biliary imaging. Anatomical imaging of the bile ducts is achieved by using a heavily T2-weighted sequence in magnetic resonance cholangiopancreatography (MRCP) .
This is accomplished by the insertion of a thin needle into the liver carrying a contrast medium to help to see blockage in liver and bile ducts. Endoscopic retrograde cholangiopancreatography (ERCP). Although this is a form of imaging, it is both diagnostic and therapeutic, and is often classified with surgeries rather than with imaging.
A radiopaque cholegraphic (contrast) agent, usually iopanoic acid (Telepaque) or its sodium or calcium salt, [2] is orally administered, which is absorbed by the intestine. This excreted material will collect in the gallbladder, where reabsorption of water concentrates the excreted contrast.

A contrast agent (or contrast medium) is a substance used to increase the contrast of structures or fluids within the body in medical imaging. [1] Contrast agents absorb or alter external electromagnetism or ultrasound , which is different from radiopharmaceuticals , which emit radiation themselves.
