Controlling sharpness, SNR and SAR for 3D FSE at 7T by end-to-end learning
Peter Dawood, Martin Blaimer, Jürgen Herrler +5
Purpose: To non-heuristically identify dedicated variable flip angle (VFA) schemes optimized for the point-spread function (PSF) and signal-to-noise ratio (SNR) of multiple tissues…
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…
Joint MR sequence optimization beats pure neural network approaches for spin-echo MRI super-resolution
Hoai Nam Dang, Vladimir Golkov, Thomas Wimmer +3
Current MRI super-resolution (SR) methods only use existing contrasts acquired from typical clinical sequences as input for the neural network (NN). In turbo spin echo sequences (T…
snapshot CEST++ : the next snapshot CEST for fast whole-brain APTw imaging at 3T
Patrick Liebig, Maria Sedykh, Kai Herz +6
CEST suffers from two main problems long acquisitin times or restricted coverage as well as incoherent protocol settings. In this paper we give suggestions on how to optimise your…
Exchange-dependent relaxation in the rotating frame for slow and intermediate exchange - modeling off-resonant spin-lock and chemical exchange saturation transfer
Moritz Zaiss, Peter Bachert
Chemical exchange observed by NMR saturation transfer (CEST) and spin-lock (SL) experiments provide an MRI contrast by indirect detection of exchanging protons. The determination o…
