Cerebral Blood Flow Regulation
Rapid vascular resistance adjustments in the brain and in the circle of Willis have been continuously measured and enhanced by signal averaging methods. Naftidrofuryl, a drug chemically similar to local anesthetics and to beta adrenergic blocking agents, increases local CBF by reducing resistance in brain and in extracerebral supply arteries. It has also been reported to affect brain metabolism...

CEREBRAL BLOOD FLOW Edited by M. Brock, C. Fieschi, D. H. Ingvar, N. A. Lassen, and K. Schurmann. (Pp. xx + 291; 113 figures; DM 58). Springer: Berlin. 1970. Measurement of the cerebral blood flow using isotope techniques is a field in which European centres have held the lead since their introduction by Lassen and Ingvar and by Harper exactly 10 years ago. Conferences at which the initiated ar...
متن کاملCerebral Blood Flow Methodology
V0 is the vascular distribution volume for the tracer in the tissue. In bolus type experiments such as H2O PET, this term is significant, whereas for inhalation of Xenon, the vascular term is not generally included, and Vo = 0. To measure CBF, the free parameters in Eq 1 are varied to obtain an optimal fit of the expression to regional uptake curves, using non-linear, least squared regression a...
متن کاملWhole blood viscosity and cerebral blood flow.
BLOOD has anomalous rheological properties, particularly in certain disease states. It may therefore be necessary to consider these properties when attempting to assess and perhaps to improve the state of a patient's cerebral circulation. So what evidence is there that cerebral blood flow (CBF) is affected by viscosity? Before attempting to answer this question, one should be aware of what infl...
