Cerebral circulation studies using inhaled 133-xenon and the gamma camera.
Cerebral Circulation Studies Using Inhaled 133-Xenon and the Gamma Camera • Inhaled 133-xenon was utilized in conjunction with the Anger gamma scintillation camera to evaluate cerebral circulation in 20 asymptomatic control subjects and in 41 patients with clinical cerebrovascular disease. Sequental cerebral scintiphotos thus obtained revealed focal areas of decreased activity in 2 of 19 contro...
متن کاملFlow Activation Studies Using Xenon-133 Clearance
Background and Purpose: Three mainstream strategies exist to detect the responses of regional cerebral blood flow to functional activation. We tested the significance of changes in raw regional cerebral blood flow data, regional cerebral blood flow data normalized by division by global cerebral blood flow (dependent model of the regional-to-global cerebral blood flow relation), and regional cer...
متن کاملAnalysis of the gamma ray spectra recorded in the use of Xenon-133 for cerebral blood flow studies.
A problem in the measurement of cerebral blood flow with 133Xenon is the presence of extra-cerebral counts in the total counts recorded with a collimated gamma ray detector looking at the brain. A method of studying qualitatively the contribution of this extra-cranial component in patients is described. This entails the sequential accumulation of gamma ray spectra recorded during the clearance ...
متن کاملRegional cerebral blood flow utilizing the gamma camera and xenon inhalation: reproducibility and clinical applications.
A modified collimator and standard gamma camera have been used to measure regional cerebral blood flow following inhalation of radioactive xenon. The collimator and a simplified analysis technique enables excellent statistical accuracy to be achieved with acceptable precision in the measurement of grey matter blood flow. The validity of the analysis was supported by computer modelling and patie...
متن کاملUsing Xenon-133 and a scintillation camera to evaluate pulmonary function.
tion has been given to evaluating pulmonary disease using radioisotopic techniques. The majority of the radioactive preparations used for these studies can be divided into two general categories : colloidal aggregates of albumin and radioactive gases. Macro aggregates labeled with 1311or 99@'Tchave been used extensivelyfor determining regional pulmonary per fusion and, as such, are useful for e...
