It
is demonstrated that non-invasive mapping of the venous microstructure
(vessel radius) is possible by using the hypercapnia-induced BOLD effect.
Furthermore, it is shown that maps of venous blood volume and vessel density
can be obtained from the same experimental setup. These parameters are
important for characterizing tumor angiogenesis and type.
