Magnetic resonance cholangiopancreatography (MRCP) uses MR imaging to visua
lize fluid in the biliary and pancreatic ducts as high signal intensity on
T2-weighted sequences: it is the newest modality for biliary and pancreatic
duct imaging. MRCP is of proven utility in a variety of biliary and pancre
atic diseases, including choledocholithiasis, congenital anatomic variants,
chronic pancreatitis, post-cholecystectomy disorders, and neoplastic duct
obstruction, MRCP is an evolving technique, but it has reached the stage of
development where it is clinically useful and of comparable accuracy to co
nventional cholangiography. With further progress, it is likely that by the
start of the new millennium MRCP will replace diagnostic endoscopic retrog
rade cholangiopancreatography as the modality of choice for imaging the bil
iary and pancreatic ducts. J. Magn. Reson. Imaging 1999;9:157-162, (C) 1999
