Magnetic resonance cholangiopancreatography

Magnetic resonance cholangiopancreatography

Magnetic resonance cholangiopancreatography (MRCP) is a non-invasive modality that provides excellent images of the gallbladder and biliary system ( Figures 71.11 and 71.12 ). These images are comparable to those obtained at endoscopic retrograde cholangiopancreatography (ERCP) or percutan - eous transhepatic cholangiography (PTC) (see Percutaneous transhepatic cholangiography and Endoscopic retro - grade cholangiopancreatography ) without the potential complications of the latter; they can demonstrate ductal abnormalities, including obstruction/stricture, stones and tumours.
