<i>R</i><sub>1</sub> and <i>R</i><sub>2</sub>* changes in the human placenta in response to maternal oxygen challenge

27 Dec 2012

Abstract excerpt

PURPOSE: Pregnancy complications such as preeclampsia and fetal growth restriction are sometimes thought to be caused by placental abnormalities associated with reduced oxygenation. Oxygen-enhanced MRI (R1 contrast) and BOLD MRI (R2 * contrast) have the potential to noninvasively investigate this oxygen environment at a range of gestational ages. METHODS: Scanning was carried out at 1.5 T under maternal air and...
