MR cholangiography and CT cholangiography of pediatric patients with choledochal cysts.

Abstract

Because non-breath-hold MR cholangiography is not invasive and does not use ionizing radiation and potentially toxic contrast agents, it is recommended as the imaging technique of choice in children with choledochal cysts. CT cholangiography can be considered as an adjunct after surgery and in patients in whom MR cholangiography is unsatisfactory.
