Fetal magnetocardiography using optically pumped magnetometers: a more adaptable and less expensive alternative?

Prenat Diagn. 2017 Feb;37(2):193-196. doi: 10.1002/pd.4976. Epub 2017 Jan 19.


Fetal magnetocardiography provides the requisite precision for diagnostic measurement of electrophysiological events in the fetal heart. Despite its significant benefits, this technique with current cryogenic based sensors has been limited to few centers, due to high cost of maintenance. In this study, we show that a less expensive non-cryogenic alternative, optically pumped magnetometers, can provide similar electrophysiological and quantitative characteristics when subjected to direct comparison with the current technology. Further research can potentially increase its clinical use for fetal magnetocardiography. © 2016 John Wiley & Sons, Ltd.
