Magnetic resonance cholangiopancreatography
Magnetic resonance cholangiopancreatography (MRCP) is a magnetic resonance imaging modality used to examine the biliary tree. It's a non-invasive modality that does not require contrast and is therefore frequently used in the evaluation of cholestasis and choledocholithiasis. If MRCP shows a stricture or obstruction of the biliary tract, an endoscopic retrograde cholangiopancreatography is usually indicated to treat the problem.
