Improved fetal blood oxygenation and placental estimated measurements of diffusion‐weighted MRI using data‐driven Bayesian modeling

Purpose Motion correction in placental DW‐MRI is challenging due to maternal breathing motion, maternal movements, and rapid intensity changes. Parameter estimates are usually obtained using least‐squares methods for voxel‐wise fitting; however, they typically give noisy estimates due to low signal‐to‐noise ratio. We introduce a model‐driven registration (MDR) technique which incorporates a placenta‐specific signal model into the registration...
