  • Title: Early diffusion-weighted MRI and 1H-Magnetic Resonance Spectroscopy in asphyxiated full-term neonates.
    Author: L'Abee C, de Vries LS, van der Grond J, Groenendaal F.
    Journal: Biol Neonate; 2005; 88(4):306-12. PubMed ID: 16113525.
    Abstract:
    AIM: To assess the predictive value of early MRI and proton MR spectroscopy ((1)H-MRS), 11 full-term neonates with severe perinatal asphyxia were studied within 48 h after birth. METHODS: T(1)- and T(2)-weighted MRI, diffusion-weighted MRI (DW-MRI), apparent diffusion coefficient of water (ADC) of the basal ganglia and parietal white matter, as well as (1)H-MRS of the basal ganglia were performed in a 1.5-Tesla magnetic field. Neurodevelopment was assessed in the survivors for at least 24 months. RESULTS: Nine of the 11 neonates had a poor outcome (7 died, 2 developed cerebral palsy). All examinations were normal in the 2 neonates with a good outcome. T(1)- and T(2)-weighted MRI were abnormal in 7, DWI was abnormal in 7, ADC was abnormal in 5, and elevated lactate/N-acetylaspartate ratios using (1)H-MRS were seen in 7 of the 9 neonates with a poor outcome. None of these 9 had completely normal MRI or (1)H-MRS findings. CONCLUSIONS: Using a combination of T(1)- and T(2)-weighted MRI, DW-MRI, ADC measurements and (1)H-MRS within 48 h after severe perinatal asphyxia, no abnormalities were seen with any of these techniques in both neonates with a good outcome.
