What is Respiratory motion compensated MR cholangiopancreatography at 3.0 Tesla about?

## Abstract ## Purpose: To reduce irregular respiratory motion‐induced artifacts in free‐breathing prospective navigator‐triggered three‐dimensional (3D) MR cholangiopancreatography (MRCP). ## Materials and Methods: A reference respiration model was estimated from the first‐five respiration periods during the initial navigator scan. With the navigator information acquired before and after triggering, the un‐acquired diaphragm position during the actual imaging was interpolated using the amplitude‐scaled reference model. Craniocaudal translational motion during imaging was retrospectively corrected using the estimated diaphragm position. T2‐weighted 3D MRCP data were acquired from 17 healthy volunteers. For quantitative analysis, contrast‐to‐noise ratio (CNR) and relative contrast (RC) of the biliary tree and gallbladder were compared using the paired t‐test. ## Results: The CNR and RC of the biliary tree and gallbladder were significantly higher (__P__ < 0.05) in the maximum intensity projection images after motion compensation. ## Conclusion: The proposed algorithm can be an effective tool to reduce the irregular respiratory motion‐induced artifacts in 3D MRCP imaging.
