Direct, longitudinal comparison of (1)H and (23)Na MRI after transient focal cerebral ischemia.


BACKGROUND AND PURPOSE (23)Na MRI may offer new insight into the evaluation of tissue injury. We performed a direct, longitudinal, morphological comparison of (1)H T2 relaxation, (1)H apparent diffusion coefficient (ADC), (23)Na content, and histopathology after cerebral ischemia to address the hypotheses that (a) (23)Na MRI is unique in comparison to (1)H… (More)
