Radionuclide bolus angiography: a technique for verification of brain death in infants and children.

Fifteen infants and children, 11 of whom had clinical brain death and four of whom were comatose, were evaluated with the radionuclide bolus study and electroencephalography. Clinical criteria for brain death included: (1) absence of spontaneous respirations, (2) absence of cephalic reflexes, and (3) unresponsiveness. Results demonstrated complete correlation among clinical examination, EEG, and radionuclide study in 79% of cases. An approach to the evaluation of the infant or child with possible brain death is outlined utilizing serial examinations, radionuclide bolus study, and electroencephalography. The radionuclide bolus study appears to be a safe, rapid, portable technique which can be used for this purpose in infants and children.
