Actually MRI uses a magnetic field through which radio waves are directed. As far as I am aware there are no demonstrated ill effects and it is used for research (a technician I was speaking to was looking at minor brain damage- he used a cohort of young jockeys, someone suggested boxers to him and he said that they did not sustain minor damage the damage was too great to look at for their study!) Volunteer pregnant and lactating > models, anyone? Maybe not just kidding.) A colleague of mine is very keen for me to have another baby so that MRI could be used to look at the suckling of a new baby via this method since it can be used to visualise flow! I really think that there is a real possibility that this technique could be used to help us understand the development of the breast.
