It is proposed to obtain information about a stress or anxiety level of a subject within a predetermined time period before, during and/or after a capture time of a fMRI scan image. Using this information, embodiments may provide additional/supplementary information that may aid, assist or otherwise improve interpretation of the fMRI scan image.

Functional magnetic resonance imaging

Disclosed herein is a medical system () where execution of machine executable instructions () causes a computational system () to: receive () a time series of a R2-star map () for a brain volume (); receive () a stimulus signal () descriptive of an occurrence of a sensory stimulus; receive () a selection of one or more seed voxels () identified in the time series of the R2-star map; calculate () a denoised time series of the R2-star map (); calculate () a correlation map () between the seed voxels and the denoised time series of the R2-star map; determine () an activated region () of the brain volume using voxels identified in the correlation map; provide () a hemodynamic response () function for each voxel and each occurrence of the sensory stimulus; and provide () a subject specific hemodynamic response function () by averaging the hemodynamic response functions.
