Journal ArticleDOI
Measuring cerebral blood flow using magnetic resonance imaging techniques
TL;DR: Magnetic resonance imaging techniques measuring CBF have developed rapidly in the last decade, resulting in a wide range of available methods and this review discusses their principles, possible pitfalls, and potential for absolute quantification and outlines clinical and neuroscientific applications.
Journal ArticleDOI
Early changes in water diffusion, perfusion, T1, and T2 during focal cerebral ischemia in the rat studied at 8.5 T.

TL;DR: The time evolution of water diffusion, perfusion, T1, and T2 is investigated at high magnetic field following permanent middle cerebral artery occlusion in the rat and two novel magnetic resonance imaging observations are reported, namely, a decrease in T2 and an increase in T1 within the first few minutes of ischemia.
Journal ArticleDOI
The measurement of diffusion and perfusion in biological systems using magnetic resonance imaging.
TL;DR: The use of the techniques to study the pathophysiology of cerebral ischaemia/stroke is described and it is hoped that the biophysical insights provided by this approach will help to define the mechanisms of cell damage and allow evaluation of therapies aimed at reducing this damage.
Journal ArticleDOI
Implementation of quantitative FAIR perfusion imaging with a short repetition time in time-course studies.

TL;DR: With this implementation of FAIR, quantitative flow maps of gerbil brains were obtained with a 3 minute time resolution in a study of the effects of reperfusion and the low values following occlusion were underestimated due to the increased transit times.
Journal ArticleDOI
Quantitative measurements of proton spin‐lattice (T1) and spin–spin (T2) relaxation times in the mouse brain at 7.0 T
TL;DR: The goal of this work is to provide regional T1 and T2 values at a field strength of 7 T for the normal mouse brain at 6 weeks and 1 year old.
