Imaging Angiogenesis and Placental Function
Preeclampsia, a hypertensive disorder, is estimated to affect 5% to 10% of pregnancies. An initiating factor in the development of the disease is placental hypoxia. Using photoacoustic imaging, we have successfully monitored longitudinal, in vivo placental oxygenation in normal pregnancy and the reduced uterine perfusion pressure (RUPP) model of preeclampsia. Our current aim is to investigate the effect two potential therapies for preeclampsia have on placental hypoxia and maternal/fetal outcome.
