Blood flow, cerebral, measurement

Neuroimaging technique for measuring cerebral blood flow, cerebral blood volume, metabolic rate, oxygen utilization and the oxygen extraction volume. 

Alterations in brain function following acute and chronic use of cannabis is nevertheless detectable using cerebral blood flow (CBF) measurements such as positron emission tomography (PET) and multi-site EEC. Although very impor-... 

Brain imaging technique that allows visualization of the brain, in order to understand which brain regions are involved in specific functions. Its functioning is based on the measurement of the regional cerebral blood flow which increases when a specific brain region is activated. Its use is similar to that of positron emission tomography (PET).
