Techniques, methods & infrastructure

Fetal magnetic resonance imaging is a routinely performed and powerful diagnostic modality that enables a high-quality assessment of the growing fetus in vivo, starting with a gestational age of 18 weeks. It is a useful method, complementary to standard ultrasound examinations, where especially the brain parenchyma and body malformations can be assessed well. In the last decades there was a constant development and a significant improvement in MRI technique, leading to a better image quality and resolution. This opened the possibility to quantify subtle structures such as the cerebellum and brainstem. The prenatal posterior fossa is a challenging field of research with many different aspects (anatomical, embryological, and functional).
