High-resolution magnetic resonance imaging of the brain in children.

Magnetic resonance image quality in infants and children has been improved by the use of spherical receiver coils and age-adjusted sequences allowing use of a high-resolution (256 X 256) image reconstruction matrix, provided adequate immobilisation is maintained. This increased resolution provides more satisfactory demonstration of the cortical mantle and details of sulci, as well as pathological processes such as periventricular oedema, infarction and tumours.
