Validity of cerebral arterial blood flow calculations from velocity measurements.

It is obvious that a noninvasive technique that can provide continuous measurements of blood flow through a cerebral artery would be very valuable for clinical and investigative purposes. The most promising approach to the development of such a technique involves the use of ultrasound for the measurement of blood flow velocity. Since blood flow through a vessel is equal to the instantaneous ave...

Coupling of local cerebral blood flow to local cerebral glucose utilization during isoflurane and sevoflurane anesthesia.

Effect of topically applied serotonin on local cerebral blood flow.

It has been hypothesized that acute lesions of the brain enlarge through an autodestructive process. Serotonin (5HT), a potent cerebral vasoconstrictor, is believed by some to mediate the process by reducing cerebral blood flow (CBF) in tissue surrounding the lesion. The hypothesis was tested in cynomologus monkeys anesthetized with ketamine and nitrous oxide. Craniectomies, 7 mm in diameter, w...

Measurement of local cerebral blood flow with iodo [14C] antipyrine.

The autoradiographic diffusible tracer technique for the measurement of local cerebral blood flow was originally designed for use with the radioactive, inert gas 131I-labeled trifluoroiodomethane and is applicable only with tracers that exhibit unrestricted diffusion through the blood-brain barrier. Because of the technical problems associated with the use of gaseous tracers, a suitable nonvola...
