Radionuclide cerebral imaging confirming brain death. 1983

J A Schwartz, and J Baxter, and D Brill, and J R Burns

Cerebral blood flow (CBF) was measured by portable radionuclide cerebral imaging (RCI) and by four-vessel cerebral contrast arteriography in 15 clinically brain-dead patients, including six children. Neither technique showed evidence of CBF, although four RCI scans showed sagittal sinus activity. Portable scanning techniques are therefore considered valid determinants of brain death and may be useful in lieu of contrast cerebral arteriography.

D007223	Infant	A child between 1 and 23 months of age.	Infants
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D011877	Radionuclide Imaging	The production of an image obtained by cameras that detect the radioactive emissions of an injected radionuclide as it has distributed differentially throughout tissues in the body. The image obtained from a moving detector is called a scan, while the image obtained from a stationary camera device is called a scintiphotograph.

D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon
D001926	Brain Death	A state of prolonged irreversible cessation of all brain activity, including lower brain stem function with the complete absence of voluntary movements, responses to stimuli, brain stem reflexes, and spontaneous respirations. Reversible conditions which mimic this clinical state (e.g., sedative overdose, hypothermia, etc.) are excluded prior to making the determination of brain death.
