Abstract
23Na magnetic resonance imaging has been used to investigate sodium changes during and after cerebral ischaemia in a gerbil model. The sodium signal decreased within 4 minutes of the onset of ischaemia, and subsequently increased between 4 and 8 minutes after the onset of reperfusion. These observations may be reflecting the redistribution of tissue sodium resulting from energy failure and recovery.
