Is it necessary to have a mother of a 7 week old stop breastfeeding for 3 days after having a MRI with contrast?? This is what the radiology department told the parents. This mother has history of a brain tumor and her oncologist will not even look at the MRI if it is not done with contrast. I do not know what type of contrast is used. Please send information asap.
