Fetal magnetic resonance imaging

The most important prenatal screening method for the detailed assessment of the fetus is ultrasound, which is often combined with colour-coded Doppler sonography. In case of sonographically diagnosed fetal pathologies or technical limitations of the ultrasound, supplementary diagnostics may be necessary. With fast MRI sequences, fetal MRI screening provides important additional information especially with regard to the most common congenital pathologies-central nervous system (CNS) pathologies (agenesis of the corpus callosum, ventriculomegaly, arachnoid cyst, pathologies of the posterior cranial fossa, dysfunction of the gyrification). Knowledge of the developmental stages of the CNS is very important for accurate clinical assessment and interpretation.
