LGALS1 and preeclampsia: The goal of this exploratory study was to investigate the potential of 19F MRI to measure placental oxygenation after i.v. injection of a Perfluoro-15-crown-5-ether (PFCE) emulsion in the gal-1 deficient Lgals1−/− knockout mouse, hypothesizing a PO2 deficit in this model of preeclampsia.
