#fetalMRI is a fascinating field. Encouraging to see such results at a lower field strength.

Advanced imaging techniques may be hampered by geometric distortion artifacts arising at air–tissue interfaces. This is made worse by the need to run highly efficient EPI-based read-outs for diffusion MRI, functional MRI, and multi-echo gradient echo sequences for T2* relaxometry, which leads to an increasing need for specialist image-based shimming techniques. Further challenges include B1 inhomogeneity-related artifacts enhanced by the presence of amniotic fluid, and SAR limitations resulting in inefficiencies in the sequences. Both B0 and B1 inhomogeneities increase with higher field strengths. Therefore, lower field strengths reduce both the impact of the aforementioned artifacts and the need for specialist correction tools. While comfort and space are paramount for any patient undergoing an MRI scan, pregnant women in the later weeks of pregnancy present a population where space and comfort is both particularly important and challenging to achieve in a standard-sized MRI bore. In addition, the number of obese pregnant women is rising – with 24% of all pregnant women in the UK and U.S. considered obese as of 2020. This presents a currently underserved population that could benefit from fetal MRI, as these women often do not receive adequate prenatal imaging due in part to the detrimental effect of increased abdominal fat on ultrasound imaging. Finally, a field strength-independent challenge concerns unpredictable and uncontrollable fetal motion, especially in early-to-mid gestation when fetuses have enough space for large displacements. This can be particularly problematic for fetal functional MRI modalities, which rely on the acquisition of the same slice location multiple times in a time-series format, to then be combined for spatiotemporal analysis. Both post-processing base techniques such as slice-to-volume registration (SVR) and prospective motion-correction techniques based on localization and tracking may be employed at low field strengths.
