Abstract
A noninvasive electromagnetic method has been examined that can effectively measure the rapid onset of vasogenic brain edema. Electrical conductivity of normal and edematous brain tissue obtained by this method at frequencies between 1 and 10 MHz is consistent with values obtained with invasive conductivity probes
