A method for foetal heart rate monitoring during magnetic resonance imaging using Doppler ultrasound

Physiol Meas. 1999 Nov;20(4):363-8. doi: 10.1088/0967-3334/20/4/303.

Abstract

A means of monitoring foetal heart rate (FHR) during magnetic resonance imaging (MRI) is presented. Foetal heart rate was measured using a modified standard Doppler ultrasound based monitor. The transducer and lead from the monitor required alteration to reduce interference and distortion in the MR images to acceptable levels. These changes enabled high quality images to be produced with insignificant additional noise and distortion when the foetal heart rate was recorded simultaneously.
