Virtually every day I get messages from mothers and health visitors querying whether mothers can continue to breastfeed after CT and MRI scans. I was told that the national guidelines had been updated some years ago to align with RANZR guidelines . Sadly this doesnt seem to have been adopted by all radiology departments from my experience.
I was lucky enough to work with Dr Gabrielle Cronin on this paper which was published recently in the Irish BMK https://rb.gy/opvtzx
Most mothers are advised to stop breastfeeding for 24 hours but there is no evidence for this as most contrast media are not orally bio available and have half lives which do not justify this duration.
