Normal cranial anatomy as seen by MRI in children aged 1 month to 21 years is comprehensively depicted in this atlas. As such it represents an invaluable tool for establishing normal baseline anatomy of the developing brain when evaluating suspected disease, trauma, or developmental delay in pediatric subjects. There are 124 normal cases presented, 62 each of boys and girls, at intervals from ages one month to 21 years. Six axial images are presented for each case. The images were obtained from Siemens, GE, and HI Standard machines. A brief introduction covers key issues in the development of white matter and special topics in pediatric neuroimaging.
