First-Trimester Biometry and Assessment of Chorionicity

1) How old am I: An accurate CRL to document the EDD is imperative.
2) Double trouble: What type of dividing membrane do I have?

This presentation will address the acquisition and documentation of appropriate pregnancy dating in the first trimester for singletons and multiple gestations, sonographic parameters to diagnose a failed first-trimester pregnancy, and the assessment of placentation/sonographic parameters to correctly diagnose chorionicity in multiple gestations.
