Fully automatic artificial-intelligence population-based quantification of placental maturation and health from a rapid 30sec functional Magnetic Resonance scan is shown in >100 women to correlate with low birth weights, spontaneous premature birth and histopathological results.
Figure 1: The proposed pipeline for the automatic placental maturation assessment is depicted consisting of the data acquisition, automatic segmentation used to calculate the placental mean T2* and the Gaussian Process regression fit or prediction, which is used to characterize placental health. All parts are discussed in the methods section.
Figure 5: Top: The placental health Z-scores are strongly related with degree of prematurity measured as GA at birth (right) and extremely low birth weight centile (left). Bottom: Z-scores grouped by histopathological examination results color-coded by GA at birth. Participants with maternal vascular malperfusion (MVM) exhibit lower Z-scores and belong to the group delivered prematurely. Chorioamnionitis does not affect Z-scores in control cases but seems to correlate to normal Z-scores in high-risk participants.
