The approximate planimetric method: a simple, rapid and reliable method for estimation of lesion size in acute ischemic stroke.

abstract：:23Na MRI changes from the acute to chronic phase were investigated in seven patients with cerebral infarcts. They showed no signal increase during the first 13 h after the stroke and revealed a definite signal increase thereafter. This reached a maximum 45-82 h after stroke and became slightly less marked in the subac...
