Overview

Magnetic resonance cholangiopancreatography (MRCP) is the diagnostic study of choice for identifying lesions of the biliary tree with sensitivity comparable to that of endoscopic retrograde cholangiopancreaticography (ERCP).

Diagnostic Study of Choice

• Magnetic resonance cholangiopancreatography (MRCP) is the diagnostic study of choice for identifying lesions of the biliary tree with sensitivity comparable to that of endoscopic retrograde cholangiopancreaticography (ERCP).
• MRCP is non-invasive and does not require contrast medium.
• Biliary stones < 5mm may be missed on MRCP.
• MRCP can identify if the lesion in the biliary tree is situated high or low.
• This identification of the location of the lesion may aid in choosing the appropriate intervention (for example, PTC for high lesions and ERCP for lesions situated lower down the biliary tree).
