Official Title: 18F-FDG PET/CT in Diagnostic Patients of Disorder of Consciousness
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).
