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).
