Recent work shows that NC-MRA for venography (NC-MRV)
can be realized by subtracting an image with all vessels
suppressed from an image with only arterial vessel
suppressed using motion-sensitized driven equilibrium
(MSDE) preparations. However, MSDE is sensitive to the
velocity of blood flow. It has difficulty to suppress
the venous vessels due to the venous blood flow rather
slow. A recent developed dark-blood preparation module,
DANTE, has minimum flow sensitive for flow suppression.
Thus, we used the MSDE and DANTE preparation together to
realize NC-MRV. Preliminary in vivo studies demonstrate
the feasibility of the proposed technique for NC-MRV.
