MRI scans are very safe. They use very strong magnetic fields and sound waves to create an image of your body. The sound waves are similar to the FM radio bandwidth used today. You will notice the MRI scan room will not have many windows and have a heavy door. This is to get radio waves and phone signals out of the scan room.
MRI’s have been performed on pregnant patients for some time. These studies are on very ill mothers where the MRI scan is deemed necessary by specialists. We avoid scanning pregnant patients in the first trimester and only perform MRI examinations on patients deemed urgent by the referring physician and our reporting Radiologist.
