Changes of positron emission tomography in newborn infants at different gestational ages, and neonatal hypoxic-ischemic encephalopathy.

Cerebral glucose metabolism was measured by (18)F-fluorodeoxyglucose position emission tomography in infants at different gestational ages and with neonatal hypoxic-ischemic encephalopathy. Thirty-six preterm and term infants at different gestational ages without brain injury were divided into four subgroups: ≤32 weeks (n = 4), 33-34 weeks (n = 5), 35-36 weeks (n = 12), and ≥37 weeks (n = 15). Twenty-four newborn infants with hypoxic-ischemic encephalopathy were divided into three subgroups: mild (n = 13), moderate (n = 7), and severe (n = 4).

Brain positron emission tomography in preterm and term newborn infants.

Objective: To study the clinical values of positron emission tomography (PET) in preterm and term newborn infants through observing brain glucose metabolism by (18)F-fluorodeoxyglucose ((18)F-FDG) PET.

Method: To observe the brain (18)F-FDG PET imaging in 9 term and 7 preterm newborn infants in the same condition after administration of 0.1 mCi/kg (18)F-FDG.
