CVR maps with fNIRS and fMRI modality and FLAIR map for one control (left column) and 2 TBI subjects (middle and right columns). The control subject shows a uniform CVR values with fNIRS and in the gray matter in fMRI. TBI-1 has a visible lesion (encephalomalacia) in the right prefrontal cortex on the FLAIR image and the lesion is also visible in CVR map (decreased CVR values) in fMRI and fNIRS. TBI-2 has no visible lesion on the FLAIR image, but a focal vascular lesion on the CVR map in fMRI (right prefontal cortex). The decrease of CVR in fMRI is also visible with fNIRS.
