High resolution computerized tomography with coronal and sagittal reconstruction in the diagnosis of brain tumors in children.

We present 4 children with brain tumors that were missed or incompletely characterized conventional computerized tomography (CT) scanning. Using high resolution CT with high dose contrast and three-dimensional reconstruction, we were able to define the anatomy of each tumor and its associated aberrant vasculature. High resolution CT scanning with reconstruction is very helpful in diagnostic problems in which conventional CT scanning fails to provide a clear diagnosis.
