Guidelines for Use of Computed Tomography Angiogram as an Ancillary Test for Diagnosis of Suspected Brain Death

Neurological determination of death (NDD) or brain death is primarily a clinical diagnosis. Ancillary testing is used in situations where clinical criteria of brain death cannot be completed fully and is used to support the clinical diagnosis. Global absence of cerebral blood flow by catheter angiography or nuclear medicine perfusion (Tc99) is the recommended gold standard for confirmation by ancillary testing. Computed tomography angiography (CTA) is a recommended ancillary test in Ontario for evaluation of absence of intracranial flow [1].
