Magnetic Resonance Cholangiopancreatography (MRCP) is a type of imaging technology that allows doctors to examine the pancreatic duct and common bile duct using images instead of surgery. It is a noninvasive test that uses a powerful magnetic field, radio waves, and a computer to produce detailed images of the hepatobiliary and pancreatic systems, including the liver, gallbladder, bile ducts, pancreas, and pancreatic duct. MRCP is a special type of MRI scan that creates detailed pictures of the pancreas, gallbladder, bile ducts, and liver. It is a type of scan that creates pictures using magnetism and radio waves. MRCP is used to diagnose diseases and conditions affecting the liver, gallbladder, bile ducts, pancreatic ducts, and pancreas, including bile duct cancer, pancreatic cancer, infection, inflammation, and gallstones and bile duct stones. MRCP is a noninvasive alternative to ERCP scans. Before the scan, you may need to stop eating and drinking for a few hours, and you may need to remove any jewelry or body piercings.
