BOLD PSF: Impact of k-space trajectories and timing on the depiction of T2* contrast
Maria Engel, Lars Kasper, Klaas P Pruessmann
The timing of BOLD-fMRI is typically chosen such that TE matches T2*. This assumes contrast being exclusively elicited by signal differences at TE. While sensible for short or TE-s…

A unipolar head gradient for high-field MRI without encoding ambiguity
Markus Weiger, Johan Overweg, Franciszek Hennel +15
Purpose: MRI gradients with a conventional, bipolar design generally face a trade-off between performance, encoding ambiguity, and circumventing the latter by means of RF selectivi…
