1) Recognize sonographic features and landmarks of a normal first trimester pregnancy. 2) Interpret sonographic findings and hCG measurements to determine a normal or abnormal gestation. 3) Analyze diagnostic criteria for nonviable first trimester pregnancy. 4) Apply sonographic findings to clarify a pregnancy of uncertain viability or unknown location.

This presentation highlights the sonographic presentations of normal and abnormal first trimester pregnancy. We will discuss the normal landmarks that are visualized during the first weeks of life. Expected hCG titers are reviewed for each landmark and discrepancies between sonographic findings and hCG levels will be discussed. The diagnostic criteria for normal and nonviable early pregnancy will be established. There will be case discussions to evaluate the findings associated with an intrauterine pregnancy of uncertain viability as well as how to assess a pregnancy of unknown location
