This is a report on our experience in the application of biomagnetism in perinatal medicine. We provide a brief description of our research work in fetal magnetoencephalography and fetal magnetocardiography in normal, preeclamptic and IUGR pregnancies, together with hemodynamics of the umbilical cord and uterine arteries, providing a new approach to biomagnetism as a non invasive imaging modality in the investigation of perinatal complications.
