Umbilical artery Doppler ultrasound waveform measurements were expressed in terms of pulsatility index (PI). Biomagnetic signals (waveforms) recorded from the IUGR umbilical artery were expressed in terms of magnetic power spectral amplitudes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In all cases, the frequency band considered was 2 to 7 Hz. The spectral amplitudes were low (mean: 117\u00b124 fT\/\u221aHz) in most (90.9%) IUGR pregnancies and high (mean: 224\u00b137 fT\/\u221aHz) in most normal pregnancies (89.5%). There was a statistically significant difference between normal and IUGR pregnancies with respect to spectral amplitudes (<jats:italic>p<\/jats:italic> &lt; 0.0001), Doppler PI (<jats:italic>p<\/jats:italic> &lt; 0.0005), pH (<jats:italic>p<\/jats:italic> &lt; 0.0005) and Apgar score (<jats:italic>p<\/jats:italic> &lt; 0.0005). Multiple linear regression analysis revealed an influence of PI, pH and Apgar scores on the biomagnetic values (ANOVA: <jats:italic>p<\/jats:italic> &lt; 0.0005).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Our data imply that biomagnetic values of the umbilical artery flow could prove to be a helpful method for the evaluation of fetal well being especially in pregnancies complicated with preeclampsia and growth restriction.
