the initial study described here tested whether nmr longitudinal relaxation time ( t1 ) correlates with brain water content in the cerebral cortex and white matter in man , and significant relationships have been demonstrated in cortex ( r = 0.65 , p less than 0.002 ) and white matter ( r = 0.94 , p less than 0.0001 ) , the latter having narrow 95 % confidence limits .
