Sulcal effacement with preserved gray-white junction: a sign of reversible ischemia.

abstract：BACKGROUND AND PURPOSE:The association between hyperthermia and early neurological deterioration, increased morbidity, and mortality in acute ischemic stroke is well known. However, the timing at which the cerebral lesion may be aggravated by high temperature has not been firmly established. The aim of this study was t...
