Probabilistic Streamline Estimation from Accelerated Fourier Velocity Encoded Measurements

Verena Knobloch¹, Julia Kowalski², Peter Boesiger¹, Sebastian Kozerke¹

Conventional streamline estimation based on a 3D velocity vector field measured by phase contrast MRI suffers from noise and partial volume effects. Fourier velocity encoding measures velocity distributions per voxel which offers the possibility of probabilistic streamline estimation. To overcome the increase in scan time, acceleration techniques are employed.
