Comparison between hydrogen clearance and microsphere technique for rCBF measurement.
Regional cerebral blood flow was measured repeatedly in anesthetized and immobilized cats under various experimental conditions by recording the clearance of inhaled hydrogen with inserted platinum electrodes and by recording the distribution of 15 mu microspheres labeled with 3 different radioisotopes. The values for both methods in normal cortical tissue were comparable (75.7 +/- 23.5 ml/100 ...

متن کاملMeasurement of rCBF by H2 clearance: theoretical analysis of diffusion effects.
Although experimental evidence now indicates that diffusion of hydrogen can influence the measured clearance curves from which local blood flow is inferred, its exact role has not yet been well defined. For this reason we have developed a theoretical treatment of the effects of diffusion near a boundary separating regions of inhomogeneous perfusion (e.g. the gray-matter interface), and reexamin...
متن کاملMeasurement of activated rCBF by the 133Xe inhalation technique: a comparison of total versus partial curve analysis.
An initial assessment of the differential sensitivity of total versus partial curve analysis in estimating task related focal changes in cortical blood flow measured by the 133Xe inhalation technique was accomplished by comparing the patterns during the performance of two sensorimotor tasks by normal subjects. The validity of these patterns was evaluated by comparing them to the activation patt...
