Magnetic resonance cholangiopancreatography (MRCP) is an MRI technique that is used to visualize the biliary and pancreatic ducts in a non-invasive manner. MRCP makes use of heavily T2-weighted MRI pulse sequences (3D T2-w SPACE or/and 2D thick slab HASTE). These sequences show high signal in static or slow moving fluids within the gallbladder, biliary ducts and pancreatic duct, with low signal of surrounding tissue. Regarding its history, MRCP was introduced in 1991. Figure shows 3D T2-w SPACE MRCP with (upper row) and without (bottom row) fat suppression. I personally prefer to use fat suppression on MRCPs.
