Synopsis

Keywords: Quantitative Imaging, FetusComprehensive anatomical and functional fetal examination at low field (0.55T) MRI, obtained using a 20min protocol in 40 pregnant women demonstrates high quality data suitable for quantitative analysis both for anatomical radiological values and for functional T2* and diffusion values, all in-line with previously reported higher field values. It opens novel avenues and widens access to fetal MRI to new groups such as the fast growing fraction of obese and overweight pregnant women, in whom comprehensive assessment by screening ultrasound may be difficult.
