A method is described for measurement of cerebral blood flow utilizing the
washout of microwave delivered heating. Using a microwave source attenuated
to achieve a brain temperature elevation of 0.5-0.75 degrees C after a 2
second exposure in the rat, cerebral blood flow was calculated from the
temperature washout curve monitored by a small thermistor implanted in the
brain. The results obtained with this method were comparable to those
obtained using the [14C] butanol method. To our knowledge this represents
the first description of a method to deliver a blood flow "indicator"
atraumatically directly into brain tissue.
