Neuroimaging assessments in two patients behaviorally diagnosed as UWS. The patient on the left presents the typical pattern of UWS (i.e., low brain metabolism as shown in blue with FDG-PET, no resting state default mode network, severe atrophy of the white matter tracts as shown with DTI, and no brain activation during motor and spatial imagery tasks). The patient on the right presents a pattern not compatible with UWS, and should hence be diagnosed as MCS*. FDG-PET: fluorodesoxyglucose-positron emission tomography, fMRI: functional magnetic resonance imaging, here the resting state is the default mode network. DTI: diffusion tensor imaging. Taken from [14].
