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…
