Synopsis

Fetal MRI is an excellent tool for estimating the fetal gestational age using the head circumference measurements. This study measures the biometry information using fast 30 sec survey scans for the measurement of fetal head circumference using 3D UNet, Bi-parietal diameter, Frontal-occipital diameter for the estimation of the fetal gestational age in the second half of gestation. The results show high accuracy in gestational age measurements which correlates well with the clinical data.
