What does a sonographer need to evaluate in the first trimester of pregnancy?

In the first trimester of pregnancy, the primary focus for a sonographer is to assess critical elements that indicate the health and development of the fetus. Evaluating the fetal heartbeat is essential because it confirms that the pregnancy is viable and that the fetus is alive. Gestational age is also measured during this period, typically through the crown-rump length, as establishing the correct gestational age is vital for monitoring growth and determining important timelines for prenatal care. Additionally, screening for any anomalies during this early stage can provide valuable information that may influence medical management or further diagnostic evaluations as the pregnancy progresses. These evaluations are foundational to ensuring both maternal and fetal health.
