Spatial specificity of the functional gradient echo and spin echo BOLD signal across cortical depth at 7 T

2025-07-31

Abstract excerpt

Functional magnetic resonance imaging (fMRI) at high magnetic field strengths (≥ 7 T) is a promising technique to study the functioning of the human brain at the spatial scale of cortical columns and layers. However, measurements most often rely on the blood oxygenation level dependent (BOLD) response sampled with a gradient echo (GE) sequence, which is known to be most sensitive to macrovascular contributions tha...
