CONSIDERATIONS OF BRAIN-DEATH ON A SPECT CEREBRAL PERFUSION STUDY

Brain death imaging is often a diagnostic challenge. Cerebral angiosci ntigraphy is extensively used for this analysis, but this test does no t allow the perfusion evaluation of the posterior fossa. The authors r eport a case in which a SPECT study showed persistence of blood frow i n infratentorial structures with total absence of cerebral (supratento rial) perfusion. This finding excluded the diagnosis of brain death.
