Improving Multi-Delay-ASL through specialized reconstruction
Ingmar Sorgenfrei, Qinyang Shou, Ingrid Barth +3
Purpose: Although image reconstruction has received relatively little attention in ASL research to date, it has the potential to address several challenges in ASL. As well as speed…
Dynamic transitions for fast joint acquisition and reconstruction of CEST-Rex and T1
Markus Huemer, Clemens Stilianu, Nick Scholand +4
Purpose: This work proposes a method for the simultaneous estimation of the exchange-dependent relaxation rate Rex and the longitudinal relaxation time T1 from a single acquisition…
MR-zero meets FLASH -- Controlling the transient signal decay in gradient- and rf-spoiled gradient echo sequences
Simon Weinmüller, Jonathan Endres, Nam Dang +2
Abstract Purpose The complex signal decay during the transient FLASH MRI readout can lead to artifacts in magnitude and phase images. We show that target-driven optimization of ind…
Enhanced and Robust Contrast in CEST MRI: Saturation Pulse Shape Design via Optimal Control
Clemens Stilianu, Christina Graf, Markus Huemer +5
Purpose: To employ optimal control for the numerical design of CEST saturation pulses to maximize contrast and stability against inhomogeneities. Theory and Methods: We appli…
