FSL MRS

FSL-MRS - end-to-end Magnetic Resonance Spectroscopy Toolbox

FSL-MRS is a suite of tools for MR Spectroscopy, including single voxel (SVS), MRS imaging (MRSI), functional MRS (fMRS), diffusion MRS (dwMRS), edited spectroscopy, etc.

This page only briefly describes the toolbox. Please refer to the FSL-MRS page for access to the full documentation and code.

The toolbox includes tools for:

Data conversion to NIfTI-MRS from multiple vendor-specific formats
Pre-processing, including coil-combination, eddy-current correction, phase alignment, etc.
Density matrix basis simulation
Spectral fitting
Quantification
Visualisation
