Artifact removal is an intrinsic challenge of resting
state fMRI data, since images are acquired without
experimental modulation of brain function, thus with no
a-priori knowledge about the signal of interest. The aim
of this study was to compare some data-driven cleaning
procedures based on single- and multi-echo acquisitions.
We qualitatively show the ability of the different
methods to remove artifacts from a dataset that includes
both typical subjects and subjects with a
neuropsychiatric disorder, characterised by restlessness
and high degree of head movements.
