โฆ Synopsis
Abstract
A stimulated echo sequence was used to obtain ^19^F NMR spectra from within a 4โml voxel in a cat brain. The time dependence of the ^19^F NMR signal from an inert gas (CHF~3~) was used to calculate the blood flow in the voxel. The position of the voxel was selected using a ^1^H MR image. ยฉ 1990 Academic Press, Inc.

## Abstract Cerebral blood flow (CBF) was measured in cat brain __in vivo__ at 2.7 T using ^2^H NMR to monitor the washout of deuterated saline injected into both carotid arteries via the lingual arteries. In anesthetized cats, global CBF varied directly with __P__aCO~2~ over a range of 20โ50 mm Hg
In vivo 'H NMR spectral editing techniques were used to monitor cerebral lactate production during remotely controlled temporary forebrain ischemia in rats. The lactate/Nacetylaspartate ( N U ) ratio correlated with suMval after ischemia and subsequent reperfusion. The lactate/NAA ratio that predict
An in vivo autoradiographic strategy is described for the measurement of local cerebral blood flow in humans by positron emission tomography, based on an application of the single-compartment model originally proposed by Kety. A variety of factors are considered upon which the successful quantitatio
