## Abstract Techniques for the quantitative imaging assessment of cerebral blood flow are presented in a cat using ^19^F NMR imaging of trifluoromethane. The input function of the indicator was acquired noninvasively, while its uptake and clearance were followed in 2βcc volume voxels from images ac

Abstract
Cerebral blood flow was quantitatively mapped by monitoring the cerebral washout of H~2~ ^17^O using rapid, singleβshot proton NMR imaging. H~2~ ^17^O acts as a freely diffusible contrast agent for proton imaging via its scalarβcoupled term, enhancing T~2~ relaxation. Measured values for CBF ranged from 29 to 106 ml/min/100 g over a range of arterial pCO~2~ between 23 and 81 Torr. Β© 1991 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 20β50 mm Hg
Previously we suggested a method for indirect detection of H 2 17 O via a combination of 1 H spin-echo sequence and 17 O decoupling. The method is based on the shortening of the water proton T 2 due to the residual spin-spin coupling with the 17 O nucleus, and on our finding that this shortening is
## Abstract We used ^17^O NMR imaging techniques to measure the H~2~^17^O concentration in a 0.8βml voxel in the cat brain following injection of an arterial bolus of enriched H~2~^17^O and during inhalation of enriched ^17^O~2~. We also measured the H~2~^17^O concentration in arterial blood during
## Purpose: To evaluate reproducibility of total cerebral blood flow (cbf) measurements with phase contrast magnetic resonance imaging (pcmri). ## Materials and methods: We repeated total cbf measurements in 15 healthy volunteers with and without cardiac triggering, and with and without repositio
## Abstract A stimulated echo sequence was used to obtain ^19^F NMR spectra from within a 4βml 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
