Perspectives in paediatric neuroradiology.
At The Hospital for Sick Children, there is a sufficient number of children who require neuroradiological procedures as to warrant a separate unit for Paediatric Neuroradiology. It functions within the Department of Radiology but is mostly involved with neurosurgery and neurology. Children under 15 kg in weight demand somewhat different technical procedures. Pneumoencephalography must be performed in a specially designed chair allowing isocentric position of the head, vertical 360 degrees rotation and side-to-side movements for tomography. Percutaneous femoral catheter cerebral angiography requires very small needles, guidewires, and catheters, so that vessels of 100 mum can be demonstrated. 2:1 magnification and subtraction are esential. Myelography is used to delineate the geography and the character of the noraml and abnormal central nervous system in infants. These studies permit accurate diagnosis of most neurosurgical and neurological diseases.
