Sensitivity & Specificity of MHASTE BOLD fMRI on MT/V5 Activation

The novel single shot mHASTE BOLD fMRI technique was tested using a more subtle stimuli pattern than the flashing checkerboard, i.e. the MT/V5 activation, which induced highly localized activation with medium level significance. mHASTE was demonstrated to be sensitive to the BOLD response in MT/V5 area with significantly improved functional specificity than EPI methods, indicating that mHASTE is mainly sensitive to micro-vasculature BOLD signals.
