Technetium 99m pertechnetate was used exclusively, because of its energy level and short physical half-life. Brain scanning provides valuable information regarding the presence of many kinds of neoplastic as well as non-neoplastic lesions. Positive scan results related to the nature of the lesions are; infections 67%, vascular lesions 66%, tumors 753, trauma 67%, subdural hematoma 88%, congenital diseases 59%, degenerative diseases 0% and convulsive disorders 33%. Scan findings were compared with the findings of plain X-rays of skull, cerebral angiography, pneumoencephalography and electroencephalography. The accuracy of scanning does not necessarily exceed that of other methods of investigation, but it provides a valuable information and increases the accuracy of diagnosis in most cases in children. The possible mechanism of positive scanning in subdural hematoma was studied. The interval between the injection and the timing of scanning was found to be an important factor in diagnosis. Brain scanning should have a place of primary importance for the work-up of children in neurosurgical practice.}, pages = {51--59}, volume = {19}, year = {1972} }
