Experience has shown us that a 1% solution of Magnevist  (gadopentetate dimeglumine) solution (Berlex Laboratories, Inc., Montville, NJ 07045-1000) works well for MRI imaging. Its NDC number is 50419-188-02. No doubt, there are other brands that would work equally well. To produce a 1% solution, mix 99 parts of water with 1 part Magnevist.
