Abstract:
There are several advantages to ultrasound examination in early pregnancy. Ultrasound performed during the first trimester confirms an intrauterine pregnancy, establishes accurate dating, and is crucial in diagnosing early pregnancy failure and ectopic pregnancy. As sonographic spatial resolution continues to improve, first trimester sonography increasingly will offer early pregnancy screening for chromosomal abnormalities and fetal structural abnormalities.
