What the sources say

MotherToBaby cites ACOG and the American College of Radiology: MRI is not associated with known risks in pregnancy and can be done in any trimester when needed, but should be used to answer an important clinical question. Most pregnancy MRIs are done without contrast; contrast may be used if the benefit outweighs possible risks. After MRI, with or without contrast, breastfeeding can usually continue; only a small amount of contrast enters milk and pumping and discarding is not usually necessary.
