The Full form of MRCP is Magnetic Resonance Cholangiopancreatography. MRCP is a medical imaging technique that uses magnetic resonance imaging to visualize the biliary and pancreatic ducts in a non-invasive manner. This procedure can be used to determine if gallstones are lodged in any of the ducts surrounding the gallbladder. MRCP uses a powerful magnetic field, radio waves and a computer to evaluate the gallbladder, liver, bile ducts, pancreas and pancreatic duct for disease. These may include tumors, stones, inflammation or infection. It is noninvasive and does not use ionizing radiation. Physician uses MRCP to evaluate patients with pancreatitis to detect the underlying cause. In patients with pancreatitis, an MRCP may be performed using a medication called Secretin to assess for long term scarring and to determine the amount of healthy pancreatic function and secretions. It also helps to diagnose unexplained abdominal pain. The magnetic field is not harmful, but it may cause some medical devices to malfunction. Most orthopedic implants pose no risk, but a person should always tell the technologist if he have any implanted devices or metal in his body. Guidelines about eating and drinking before the exam vary between facilities. Unless a person is told otherwise, he must take his regular medications as usual.
