Left panel: Myometrial fit for and d* using the standard IVIM and the myometrial model (Equation ((1))) and T2 relaxation time of maternal blood and myometrium using the myometrial model. T2 relaxation times are consistent with values previously reported in the literature.21, 22 Right panel: placental fit for and d* using the standard IVIM and the DECIDE model (Equation ((2))), and and T2 relaxation time of fetal blood with the DECIDE model. The placenta shows a significant third compartment (). Fetal blood T2 relaxation time is lower than the literature value for adult blood T2.21
