MR of obstetric diseases in pregnancy

Pregnancy predisposes women to a range of obstetric complications, which are often multifaceted and perplexing. Imaging plays a decisive role in the diagnosis and management of these complications. Ultrasonography (USG) and magnetic resonance imaging (MRI) confer the least risk to the fetus and should be the favored examinations for evaluating these complications. MRI does not expose mother and fetus to ionizing radiation and provides cross-sectional images in any plane with high anatomic resolution even without intravenous contrast administration. Knowledge of appositeness of imaging is necessary for precise patient management. This chapter provides comprehensive update of spectrum of non-fetal obstetric diseases affecting pregnant patients.
