A new sequence is presented which uses the advantages of a Twisted Projection Imaging trajectory design to reduce measurement time in radial proton imaging. The SNR of this sequence is higher when compared to standard 3D radial imaging. It is shown that this sequence can be used for fast and accurate T1 measurement with a Variable Flip Angle approach. Especially in DCE-MRI this sequence has advantages for precontrast as well as dynamic measurement. It could be used where conventional radial approaches to DCE-MRI suffer from lower SNR and undersampling artifacts.
