Abstract
Obstetric risks, associated with pre-eclampsia, such as maternal age and pre-existing conditions are on the rise, along with the risk of ectopic calcification and placental vascular dysfunction. We investigated Slc20a2 mice models through non-invasive commercialized and synergistic ultrasound and photoacoustic imaging, which provide dual-wavelength images and radio frequency data. The increased ectopic placental vascular calcification model exhibits reduced fetal growth and decreased postnatal bone mineral density. Our experiments established a significant difference in both placental function and structural differences between normal and diseased placentas through the provided oxygen saturation and quantitative ultrasound spectral parameters.
