MRI in radiation-induced myelopathy and pharyngocutaneous fistula.

abstract：:We studied the changes in brain water diffusion in childhood as seen on diffusion-weighted MRI in 30 children from 1 day of life to 17 years to provide a data base and to investigate the correlation of diffusion changes with known patterns of white matter maturation.
