In this educational talk, risks associated with MRI specific to imaging the fetus and the pregnant woman will be discussed. Specifically, this talk will cover the safety concerns and data available on topics such as high magnetic field strength imaging (e.g. 3 Tesla), imaging early gestational age fetuses and pregnant women, using technologies such as parallel radiofrequency transmission or radiofrequency shimming and high dielectric constant pads to mitigate transmit field nonuniformities, imaging position of the pregnant women, e.g. supine or lateral, and imaging pregnant women and not the fetus.

Fetal magnetic resonance imaging (MRI) at low field strength (0.55T) offers unique insights into prenatal development. Low field fetal MRI images the entire uterus—including the fetal brain, body, heart, and placenta—as well as the maternal pelvis and cervix. At low field strengths, there are reduced susceptibility-induced artifacts and longer T2* values, allowing not only structural imaging, but quantitative imaging such as T1 and T2* mapping, and diffusion tensor imaging. Low field strength facilitates a homogeneous field in a wide bore, increasing accessibility especially at late gestational ages. This presentation will provide an overview of low field fetal MRI.

The placenta is an important organ that serves as a critical interface between a mother and her fetus. Deterioration in placental wellbeing throughout pregnancy is a leading cause of perinatal morbidity and mortality. Monitoring placenta throughout pregnancy is therefore a critical component of antenatal care. MRI provides a tremendous potential for monitoring placental structure and function. Development of quantitative MRI measures for placental health would increase our ability to detect placental insufficiency and could motivate and evaluate potential therapeutic interventions.

In this presentation, I summarize recent advances in fetal brain MRI and discuss its diagnostic value in clinical practice. A wide range of topics will be introduced including the process of fetal brain development, fetal brain clinical and scientific MRI sequences, normal imaging features of fetal brain structure on MRI, two-dimensional measurement and three-dimensional volume brain segmentation on fetal brain MRI, MRI diagnosis of different congenital brain malformations in fetuses such as cortical dysplasia, ventriculomegaly, holoprosencephaly, agenesis of the corpus callosum, tuberous sclerosis, vein of Galen malformations, and posterior cranial fossa malformation, et al.
