As functional analyses move toward finer detail and higher resolution, sources of noise that were nuisances are now becoming more significant. While noise removal is well studied in lower-resolution, gradient echo BOLD-weighted imaging, it is not as well understood in high resolution VASO. We examine the efficacy of physiological noise cleaning methods that are commonly used in many fMRI studies.
