Assessment of physiological noise modelling methods for functional imaging of the spinal cord

► Physiological noise correction methods for spinal cord fMRI were evaluated. ► Physiological Noise Model was found to outperform Selective Averaging Filter. ► Heart Rate and Respiration Volume Time had a negative impact on the statistics. ► Cardiac and respiratory impulse response functions were not beneficial. ► Pre-whitening in addition to physiological noise correction was advantageous.
