Inconsistent breathholds during 3D dynamic DCE MR
imaging of the abdomen are a major cause of motion
artifacts. In this study we compared motion sensitivity
of dynamic 3D-DIXON FFE to end-breath hold motion
between interleaved1 and grouped2 peripheral ky-kz
viewsharing. The acquisition of the complete peripheral
kykz at the end of the breath hold makes gouped
viewsharing less sensitive to breathing induced motion
at the end of the acquisition. It also allows for a
higher temporal resolution in the early dynamics, which
is especially beneficial for capturing early arterial
phases of abdominal MR imaging.
