Sammanfattning

• Standard MRI methods acquire Fourier-encoded data on a regularly spaced Cartesian
grid. Noncartesian MRI methods abandon this grid and instead acquire data along
arbitrary trajectories in k-space, which can lead to advantages such as motion robustness
and more flexible pulse sequence design.
• Zero Echo Time (ZTE) imaging is a specialised form of MRI with an inherently noncartesian three-dimensional radial trajectory (Ljungberg et al., 2021). ZTE imaging has
many interesting benefits, such as near silent operation, but also technical challenges
such as dead-time gap artefacts (Froidevaux et al., 2021).
• We have developed a toolbox, named Radial Interstices Enable Speedy Low-volume
imagING (RIESLING), tuned for high performance reconstruction of MRI data acquired
with 3D noncartesian k-space trajectories. While our group has a focus on ZTE imaging,
RIESLING is suitable for all 3D noncartesian trajectories
