There is a widespread lack of familiarity with the normal appearance of the fetal brain in the early second trimester (12-18 weeks), particularly in MRI. Interpreting these images is challenging because of the continuous fetal motion, small size of structures, and immature appearance of the brain. This educational exhibit aims to increase awareness of the appearance of the fetal brain between 12- and 18-weeks gestation by presenting images of normal fetuses and establishing a correlation with same day ultrasound. All fetuses included in this exhibit were proven to have normal brains on late gestation fetal and/or post-natal brain MRI.

After viewing this exhibit the reader will (1) recognize the normal appearance of the brain in the early second trimester, (2) understand the specific developmental trajectories of major structures (ventricles, corpus callosum, etc…), (3) establish a correlation between the sonographic appearance and the fetal MRI.

The fetal ganglionic eminence (GE) is a transient structure in the developing human brain, playing a crucial role in the formation of the cerebral cortex and other critical brain regions. The GE is primarily responsible for the production of GABAergic interneurons, which are essential for the proper functioning of the cerebral cortex.
Understanding its anatomy and pathology is essential for identifying potential developmental disorders that may arise during prenatal life.
Fetal MRI has emerged as a powerful tool in the assessment of brain development, offering high-resolution images that can reveal subtle changes in the anatomy of the GE.
Through the use of fetal MRI radiologists can identify various alterations in the GE, such as cystic cavitations, enlargement, and other morphological changes that may indicate serious malformations in brain development, such as hemimegalencephaly or other cortical malformations. One of the significant advantages of fetal MRI is its ability to provide a comprehensive view of the fetal brain, enabling the identification of not only the GE but also its relationship with surrounding structures such as the lateral ventricles or the thalamus, which can further complicate the clinical picture.
By utilizing fetal MRI to study the GE, it becomes possible to detect these disruptions early in gestation, potentially allowing for timely interventions and better parental counseling. Read More
