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
