Clinical value of PET/CT imaging of cerebral blood flow and metabolism in patients with chronic disorders of consciousness

Objective To investigate the value of PET/CT imaging of cerebral glucose metabolism (CGM) and cerebral blood flow (CBF) in evaluating chronic disorders of consciousness (CDC). Methods A total of 10 CDC patients (5 males, 5 females, age (50. 9 ±17.2) years) and 10 healthy controls (5 males, 5 females, age ( 52. 0 ± 10.3) years) from January 2016 to March 2017 were recruited to perform brain PET/CT of CGM and CBF.
