Abstract:
Since its introduction in the 1950s, ultrasonography in pregnancy has been helpful in determining gestational age, detecting multiple pregnancies, locating placentas, diagnosing fetal anomalies, evaluating fetal well-being, and guiding obstetricians with in utero treatment. We review current standards and controversies regarding the indications, safety, accuracy, and limitations of ultrasonography in pregnancy.
