Can MRCP replace the diagnostic role of ERCP for patients with choledochal cysts?

MRCP showed overall good accuracy in the detection and the classification of choledochal cysts and revealed associated cholangiocarcinoma and choledocholithiasis with excellent accuracy. MRCP, therefore, may supersede the diagnostic role of ERCP for the patients with choledochal cysts. However, MRCP showed limited capacity to detect minor ductal anomalies or small choledochocele.
