3D MRCP scans can be as long as 4-5 minutes long, during which time physiological motion artefact may result in reduced image quality. Here we developed a Navigated 3D MRCP sequence with compressed sensing to allow a reduced acquisition time. The results from 7 volunteers shows that the MRCP with CS produced good quality images similar to the standard sequence, however, with the CS the acquisition time was reduced by around 50%. Therefore we conclude that the use of CS with MRCP has the potential to reduce motion related artefacts and improve workflow efficiency
