Abstract

In Japan, brain death has been diagnosed based on deep coma, fixed and dilated pupils, loss of brainstem reflexes, flat electroencephalography (EEG), and loss of spontaneous respiration. However, an international consensus published in 2020 proposed that various imaging techniques evaluating cerebral blood flow instead of EEG should be used as ancillary tests to negate false-positive diagnoses of brain death. This article describes the imaging techniques used to determine brain death.
