According to the American College of Radiology, less than 0.04% of the intravenously administered gadolinium-based contrast media is excreted into breastmilk. It has a plasma half-life of 2 hours, and it out of the bloodstream in 24 hours, assuming normal kidney function. Less than 1% of the gadolinium excreted in breastmilk is absorbed by the infant, leading to far less exposure to gadolinium as compared to the dose used for infants. It is therefore considered unnecessary to interrupt breastfeeding after an MRI with contrast. There may be a change in the taste of the milk for a few hours after the MRI, but it is not considered harmful to the child.
