In vivo investigation of the multi-exponential T2 decay in human white matter at 7T: Implications for myelin water imaging at UHF
Vanessa Wiggermann, Alex MacKay, Alexander Rauscher +1
Multicomponent T2-mapping using a gradient and spin-echo (GraSE) acquisition has become standard for myelin water imaging at 3T. Higher magnetic field strengths promise SNR benefit…
Bias field correction of MPRAGE by an external reference -- The poor man's MP2RAGE
H. Olsson, G. Helms
Purpose: To implement and evaluate a sequential approach to obtain semi-quantitative T1-weighted MPRAGE images, unbiased by B1 inhomogeneities at 7T. Methods: In the reference grad…
Correction of FLASH-based MT saturation in human brain for residual bias of B1-inhomogeneity at 3T
Gunther Helms, Nikolaus Weiskopf, Antoine Lutti
Background: Magnetization transfer (MT) saturation reflects the additional saturation of the MRI signal imposed by an MT pulse and is largely driven by the saturation of the bound…
Reducing bias in dual flip angle T1-mapping in human brain at 7T
H. Olsson, M. Andersen, R. Wirestam +2
Purpose: To address the systematic bias in whole-brain dual flip angle (DFA) T1-mapping at 7T by optimizing the flip angle pair and carefully selecting RF pulse shape and duration.…
