CE MRA of the Liver
Which injection rate and amount of Gadolinium works best for CE MRA of the liver with a good portal venous contrast? We have a power injector and a 1.5 T system. With a flow rate of 3 ml/sec and 20 ml contrast agent the arterial contrast but the portal phase could be better. Our MRA's are done with 15 sec. scan time for one breath hold.

What is the advantage of black blood cine over standard bright blood cine?
