The assessment placental perfusion using dynamic contrast enhanced MRI is of increasing importance for early prediction of fetal growth restrictions and vascular complications during pregnancies. To assess differences in the placenta perfusion in experimental studies analysis is performed as an average over the whole placenta. However, the mouse placenta consists of two different functional zones and differentiating the two compartments may lead to additional important information. In this work placenta functional compartments were successfully differentiated using time-to-peak values of the contrast agent time curve. Perfusion analysis of both compartments revealed significant differences which could be beneficial for further studies.
