Venous
cerebral blood volume (CBVv) is key to the BOLD response, but could not be
measured directly until the advent of the VERVE technique. We present a new
method for measuring changes in CBVv using hyperoxia. This new method has a
high signal-to-noise ratio enabling high spatial (223mm) and temporal
(TR=2.4s) resolution. In this work we show measurements of relative changes
in CBVv. However with refinements to the acquisition and analysis it will be
possible to measure the percentage change in CBVv.
