Continuous measurement of regional cerebral blood flow using krypton-81m.
We have developed a new method for taking continuous measurements of rCBF by means of continuous infusion of 81mKr. Using this method, it is possible to follow the sequential changes in blood flow of various brain regions continuously. The method makes it possible to observe the sequential changes in CBF following drug administration, motor activation and various kinds of stimulation, and, furt...
متن کاملImproved Method for Noninvasive Measurement of Regional Cerebral Blood Flow
A clinical method for noninvasive measurement of regional cerebral blood flow (rCBF) and blood volume (rCBV) is described, based on Obrist's 10 minute, desaturation method after 1 minute inhalation of Xe. Sixteen collimated probes are placed over both hemispheres and brain stem-cerebellar regions. End-tidal Xe curves are used for correction of recirculation. KEV discriminators are set to record...
متن کاملRegional cerebral blood flow in Alzheimer's disease.
Neural networks have been successfully applied to brain perfusion images to classify patients with Alzheimer's disease from normal or other patient populations. Given the recognition that Alzheimer's disease constitutes a heterogeneous disorder, the identification of subgroups sharing common functional brain deficits would constitute a further improvement in the utility of such methods. Therefo...
متن کاملSex differences in regional cerebral blood flow.
Regional cerebral blood flow was measured by the 133-xenon inhalation method during resting in 38 healthy men and 38 healthy women matched pairwise for age in the range 18-72 years. The results showed 11% higher global flow level in the women in all ages. A similar and significant regression of flow by age was seen for both sexes. The regional flow distribution also showed some sex-related diff...
متن کاملNewer techniques of cerebral blood flow measurement.
• A variety of methods for measuring cerebral blood flow have been developed in the past 25 years since Kety and Schmidt developed their method based on the Fick principle. None of the currently used methods approaches the clinical ideal, since none of the techniques are accurate, reproducible and noninvasive. Most accurate techniques involve catheterization of internal carotid artery and/or ju...
