This is not your average birth video. German researchers have used Magnetic Resonance Imaging to peer inside a woman's body during labor, a medical first that sheds light on the birth process. The researchers, from Charité University Hospital in Berlin, created the 30-second movie using cinematic MRI, a technique that strings together snapshots from deep inside the body. "Knowledge about the mechanism of labor is based on assumptions and radiographic studies performed decades ago," the researchers wrote in their study, published in the June issue of the American Journal of Obstetrics & Gynecology.

My concern is about the magnetic field generated by MRI and its possible effects on the newborn. While we have a fairly long experience with ultrasound, the same is not true about MRI during pregnancy and labor.

Appears an excellent study which used a real-time MRI series during delivery of the fetal head. Delivery occurred by progressive head extension. However, extension was a very late movement that was observed when the occiput was in close contact with the inferior margin of the symphysis pubis, occurring simultaneously with gliding downward of the fetal head. This observational study shows, for the first time, that birth can be analyzed with real-time MRI. MRI technology allows assessment of maternal and fetal anatomy during labor and delivery. Many thanks drrathore for focusing on important advances in the medical sciences that sheds light on the birth process. |

Here is a more direct link to the article and video. Looking at the imaging parameters, although it is a turbo spin echo sequence, it appears that the video is a probably a slightly accelerated ciné version of events, but supremely fascinating nonetheless. New technologies such as compressed sensing (which means that less k-space has to be filled in order to get a good final picture) may move us closer to real-time dynamic MRI, which could have significant implications in: labour (as above), pelvic floor dysfunction, joint mobility assessment, tracheobronchial disorders, sleep apneoa, swallowing dysfunction and more. Yes, yoram, we don't know much about the effects of magnetic fields in pregnancy and the newborn, but it is only a 1.0T magnet and so the flux will be relatively little. Main concerns are energy deposition and electric current induction, but these again will be very little from the low field strength.
