Correction for the Presence of Intravascular Oxygen-I5 in the Steady-State Technique for Measuring Regional Oxygen Extraction Ratio in the Brain: 2. Results in Normal Subjects and Brain Tumour and Stroke Patients


Values of regional cerebral oxygen extraction ratio and oxygen utilisation obtained with the oxygen-IS steady-state inhalation technique have been found to be overestimated due to the signal from intravascular ox­ ygen-IS. A previously described method to correct for this intravascular component has been applied to a series of studies on normal subjects… (More)
