- Real-time ultrasound was used in 654 consecutive pregnancies to obtain standard growth parameters for the fetal brain. Measurement of the width of the lateral ventricle (LVW) and hemisphere and their relationships to menstrual age, biparietal diameter, and birth weight were determined. The growth of the LVW was to a great extent independent of birth weight but dependent on menstrual age. Thirteen fetuses with a single ventricular width measurements exceeding +2 SD from the mean were separately evaluated, and all but one case were found to be normal.

- Total and regional cerebral glucose metabolism (CMRgl) was measured by positron emission tomography with 2-(F-18) fluoro-2-deoxy-D-glucose ((18)FDG) in 20 term infants with hypoxic ischemic encephalopathy (HIE) after perinatal asphyxia. All infants had signs of perinatal distress, and 15 were severely acidotic at birth. Six infants developed mild HIE, twelve moderate HIE, and two severe HIE during their first days of life. The positron emission tomographic scans were performed at 4-24 d of age (median, 11 d). One hour before scanning, 2-3.7 MBq/kg (54-100 µCi/kg) (18)FDG was injected i.v. No sedation was used. Quantification of CMRgl was based on a new method employing the glucose metabolism of the erythrocytes, requiring only one blood sample. In all infants, the most metabolically active brain areas were the deep subcortical parts, thalamus, basal ganglia, and sensorimotor cortex. Frontal, temporal, and parietal cortex were less metabolically active in all infants. Total CMRgl was inversely correlated with the severity of HIE (p < 0.01). Six infants with mild HIE had a mean (range) CMRgL of 55.5 (37.7-100.8) mol.min(-1).100 g(-1), 11 with moderate HIE had 26.6 (13.0-65.1) µmol.min(-1).100 g(-1), and two with severe HIE had 10.4 and 15.0 µmol.min(-1).100 g(-1), respectively. Five of six infants who developed cerebral palsy had a mean (range) CMRgl of 18.1 (10.2-31.4) µmol.min(-1).100 g(-1) compared with 41.5 (13.0-100.8) µmol.min(-1).100 g(-1) in the infants with no neurologic sequela at 2 y. We conclude that CMRgl measured during the subacute period after perinatal asphyxia in term infants is highly correlated with the severity of HIE and short-term outcome.
