Allergic to contrast for MRI

I recently learned the hard way that I am allergic to contrast dye for a MRIs.

Do any of these need contrast dye?:

MVD

GammaKnife

Radiofrequency

Thank you in advance

MRI for MVD does not have to be contrast ---it just has to eliminate MS or brain tumor --- will most likely not show TN

There is a fiesta MRI that is the best type to find compressions --- maybe somebody has answers for others.

Do they need to use contrast to perform the procedures?

I know with my Gamma knife they did both MRIs with and without contrast but they said it was just to get a better picture of where they would be shooting the radiation at.
