Frequency of common bile duct motion artifacts caused by inferior vena cava pulsation on magnetic resonance cholangiopancreatography.

Purpose: We assessed the frequency of common bile duct (CBD) motion artifacts caused by inferior vena cava (IVC) pulsation on magnetic resonance cholangiopancreatography (MRCP).

Methods: We retrospectively evaluated CBD motion artifacts in 4 MRCP sequences from each of 115 consecutive patients.

Results: We observed 37 (32.
