In recent years physicians have used a variety of laboratory studies as confirmatory tests in the diagnosis of brain death. The most widely used test has been the EEG. However, with the development of newer technologies capable of measuring other parameters of brain functions, other laboratory studies are playing an increasingly important role in confirming brain death. In this article, we discuss the role of one of these newer tests, the radioactive brain scan, and compare its advantages and limitations with the EEG.
