title: Regional cerebral mode transit time and the derivative of the regional cerebral function recorded for intravenous administration of a non-diffusible tracer.
abstract: The meaning of the time from origin to first peak and from peak to peak of the derivative of the regional cerebral functions recorded after intravenous administration of a non-diffusible tracer is analyzed. Data obtained by cerebral and cardiac monitoring and evaluation of both times in patients with carotid thrombosis, indicates that the time from origin to first peak may be a better estimate of regional cerebral mode transit time than the time from peak to peak.
