Summary

Magnetic resonance imaging (MRI) does not impact fetal heart rate or movement. This study found no significant changes in cardiotocographic (CTG) parameters or fetal activity after MRI scans during late gestation.

Area of Science:

  • Medical Imaging
  • Obstetrics
  • Fetal Monitoring

Background:

  • Antenatal ultrasonography (US) is used to detect fetal anomalies.
  • Cardiotocography (CTG) assesses fetal well-being through heart rate and movement.
  • The safety of Magnetic Resonance Imaging (MRI) during pregnancy requires evaluation.

Purpose of the Study:

  • To investigate the effects of MRI on fetal cardiotocographic (CTG) parameters.
  • To assess MRI's impact on fetal movement incidence.
  • To determine MRI safety for fetuses in the third trimester.

Main Methods:

  • Sixteen pregnant women in their third trimester underwent MRI scans.
  • Fetal heart rate (FHR), short-term variation (STV), and fetal movements were analyzed before and after MRI.

  • High-field strength MRI (1.5 T) with strong gradients was utilized.

    • Main Results:

    • No statistically significant changes were observed in basal FHR (P = 0.158).
    • Short-term variation (STV) remained within normal limits post-MRI (P = 0.196).
    • Fetal movement incidence showed no significant difference after MRI (P = 0.98).

    Conclusions:

    • High-field strength MRI with powerful gradients does not adversely affect fetal heart activity.
    • MRI examination does not alter fetal movement incidence.
    • The study supports the safety of MRI for fetal assessment in the third trimester.
