摘要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.
