Pregnant Trauma: Imaging findings of maternal and fetal injury

TEACHING POINTS
During pregnancy, women undergo significant physiologic and anatomic changes. Trauma in pregnant patients is important as it involves both the mother and the fetus. Therefore, radiologists should be familiar with imaging evaluation and interpretation of the traumatized pregnant patient. Radiologists provide an important role in diagnosis of common pregnancy-associated injuries in trauma such as placental abruption, fetal demise, and uterine rupture. Multidiscplinary approach involving OBGYN, emergency medicine, and radiology is important in choosing the appropriate modality of imaging in pregnant trauma patients.
