“MARS: Magnetic Resonance Study: A Novel Assessment of Placental Function”
The objective of this study is to evaluate functional MRI as a tool to study placental transfer of oxygen and nutrients during the third trimester of pregnancy in obese women, women with pregestational diabetes and healthy low risk women without these conditions (controls). The investigators hypothesize that altered placental function, including diminished placental oxygenation and enhanced placental transport of lipids and metabolites will be seen in obese and pregestational diabetics as compared to controls.
Diagnostic Test - functional MRI
Participants will undergo a functional MRI using multiple imaging modalities.
