We examined the fractal pattern of cerebral computerized tomography images in 158 normal infants, aged 0-3 years, based on the quantitative analysis of chaotic theory. Results showed that the fractal dimension of cerebral computerized tomography images in normal infants remained stable from 1.86-1.91. The normal distribution range in the neonatal period, 1-2 months old infants, 1-2 year old infants, and of 2-3 year old infants was 1.88-1.90 (mean: 1.891 3 ± 0.006 4), 1.89-1.90 (mean: 1.892 7 ± 0.004 5), 1.86-1.90 (mean: 1.886 3 ± 0.008 5), and 1.88-1.91 (mean: 1.895 8 ± 0.008 3), respectively. The spectrum width of the multifractal spectrum (△α) in normal infants was 1.4618. These data suggest that the spectral width parameters of the multifractal spectrum and the fractal dimension criteria in normal children may be useful as a practical specific parameter for assessing the fractal mode of brain development in normal infants.

The spectrum width of the multifractal spectrum (Δα) in normal infants was 1.4618. These data suggest that the spectral width parameters of the multifractal spectrum and the fractal dimension criteria in normal children may be useful as a practical specific parameter for assessing the fractal mode of brain development in normal infants.
