Increased vulnerability of the blood-brain barrier to experimental subarachnoid hemorrhage in spontaneously hypertensive rats.

abstract：BACKGROUND AND PURPOSE:Diffusion-weighted MRI can demonstrate decreases of the apparent diffusion coefficient (ADC) of brain tissue water shortly after the onset of ischemia. To further elucidate underlying mechanisms, this study extended diffusion assessment to intracellular metabolites in rat brain in vivo before, du...
