The procedure is a standard part of prenatal care in many countries, as it can provide a variety of information about the health of the mother, the timing and progress of the pregnancy, and the health and development of the embryo or fetus. The International Society of Ultrasound in Obstetrics and Gynecology ISUOG recommends that pregnant women have routine obstetric ultrasounds between 18 weeks’ and 22 weeks’ gestational age the anatomy scan in order to confirm pregnancy dating, to measure the fetus so that growth abnormalities can be recognized quickly later in pregnancy, and to assess for congenital malformations and multiple pregnancies twins, etc.
Performing an ultrasound at this early stage of pregnancy can more accurately confirm the timing of the pregnancy, and can also assess for multiple fetuses and major congenital abnormalities at an earlier stage. There is no difference, however, in perinatal death or poor outcomes for infants. Below are useful terms on ultrasound: .
In normal state, each body tissue type, such as liver, spleen or kidney, has a unique echogenicity. Fortunately, gestational sac, yolk sac and embryo are surrounded by hyperechoic brighter body tissues. Traditional obstetric sonograms are done by placing a transducer on the abdomen of the pregnant woman. One variant, transvaginal sonography, is done with a probe placed in the woman’s vagina.

The sensitivity of this only recently eclipsed by NIPT. An ultrasound screening test is non-invasive and does not have any side effects or complications.
