Reducing bias in dual flip angle T1-mapping in human brain at 7T

Autor: Olsson, H., Andersen, M., Wirestam, R., Lätt, J., Helms, G.

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. Theory and Methods: Spoiled gradient echoes can be used to estimate w

Notes on quantitative susceptibility mapping reconstruction accuracy under challenging conditions: Phantom measurements and simulations

Autor: Lundberg A, Lind E, Knutsson L, Wirestam R

Publikováno v: Journal of Medical and Scientific Research, Vol 10, Iss 3, Pp 111-117 (2022)

Magnetic susceptibility can be assessed by quantitative susceptibility mapping (QSM), based on measured magnetic resonance imaging (MRI) phase data. The QSM reconstruction process is, however, mathematically challenging and still not fully robust. A
