Generalized Lorentzian Tensor Approach (GLTA) as a Biophysical Background for Quantitative Susceptibility Mapping

摘要

PurposeQuantitative susceptibility mapping (QSM) is a potentially powerful technique for mapping tissue magnetic susceptibility from gradient recalled echo (GRE) MRI. Herein we aim to derive the relationships between GRE signal phase and the underlying tissue microstructure and magnetic susceptibility at the cellular level.
