Measurement of cerebrovascular changes in cats after transient ischemia using dynamic magnetic resonance imaging.

Abstract

The hemodynamic behavior we observed in our model reflects the independent responses of the cerebral blood volume and flow index to ischemic insult. Measurements acquired by our method were consistent with the temporal behavior reported in previous radionuclide studies. Susceptibility-contrast nuclear magnetic resonance tomographic imaging proved to be valuable in detecting and quantifying both immediate and subsequent changes in the hemodynamic state of the ischemic and hyperemic feline brain.
