Abstract Accurate gestational dating is of paramount importance and the cornerstone for management of pregnancies, easily reproducible sonographic fetal biometric parameters for gestational dating are clinically important for the optimal obstetric management of pregnancies. This is especially true in determining timing of a variety of gestational tests, assessing adequacy of growth and timing of delivery for the optimal obstetric outcome (Chavez et al., 2007). The development and practice of fetology has been dependent on advances in the field of prenatal imaging. Without the ability to accurately visualize the structure and well-being of the fetus within its own intrauterine environment, it would not be possible to diagnose or treat the range of abnormalities that can now be addressed by the multidisciplinary fetal health care team. Rapid advances in the technologic basis of two imaging methods ultrasonography and magnetic resonance imaging (MRI) have resulted in highly accurate visualization of the fetal anatomy. Ultrasonographic imaging is an integral part of obstetric practice today. In the United States, it is performed in the majority of all pregnancies (Martin et al., 2003). |
