[Efficiency and efficacy of neuroradiologic diagnosis of brain diseases in childhood].

The younger the child, the more pronounced are the distinctions from adults in brain anatomy, structural changes, and neuropathological symptoms. Ultrasonography can give information about most age-typical conditions when the fontanelles are open. Craniocerebral malformations or tumors should always be shown by computed tomography. Magnetic resonance imaging has above all provided improved diagnostic information about myelination, nonhemorrhagic parenchymal changes, and infratentorial and peribasilar processes. Indications for angiography are limited in general to cases of vascular malformations. Isotope scintigraphy, ventriculography and pneumencephalography are indicated only in exceptional cases.
