Persistent Vegetative State

Brief summary

Clinical examinations are difficult to discriminate between vegetative state and minimally conscious state. the diagnostic and prognostic usefulness of neuroimaging methods has not been established in a clinical setting. we will do a forward study of PET imaging in disorders of consciousness patients, and validate with clinical assessments with the coma recovery Scale-Revised(CRS-R).

Detailed description

Every patient need to be conducted the PET/CT scanning two times.The first time is resting state.The second time is stimulated state by watching a vedio.
