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.

In recent years, 7 Tesla MRI has become a valuable tool in the field of neuroimaging. Ultra-high field strength provides a superior signal-to-noise ratio, which is particularly advantageous for structural and vascular imaging, as well as MR Spectroscopy. Despite the many advantages, artifacts abound at 7T and limit its translation. Furthermore, the high SAR of these scanners and regulatory restrictions imposed by the FDA can limit accessibility for pediatric patients. This educational exhibit aims to delve deeper into these issues and: 1. Review the commercially available hardware. 2. Summarize regulatory and safety constraints. 3. Highlight the advantages of 7T for structural, vascular, and MRS. 4. Illustrate artifacts and limitations. 5. Present examples of brain abnormalities at 7T. References: 1.
