Effect of Caffeine on Functional and Perfusion MRI
Grant Start Date: 2005-04-18
Grant End Date: 2009-01-31
Caffeine is the most widely consumed neurostimulant in the world, but it also impacts the diameter of blood vessels in the brain. An individual's level of caffeine consumption and how long prior to the fMRI scan they had their coffee may interfere with an accurate measurement of the BOLD signal. This study seeks to investigate these parameters for their effect on the BOLD signal and cerebral perfusion levels.
