Soft markers are variations from normal anatomy, which are more common in aneuploid fetuses compared to euploid ones. Sometimes a woman may be uncertain of the date of her last menstrual period, or there may be reason to suspect ovulation occurred significantly earlier or later than the fourteenth day of her cycle. The procedure is a standard part of 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. Coincidentally, most also happen by 7 weeks fetal dating ultrasound. The bright white circle center-right is the head, which faces to the left. One variant, a transvaginal sonography, is done with a probe placed in the woman's. Dating is more accurate when done earlier in the pregnancy; if a later scan gives a different estimate of gestational age, the estimated age is not normally changed but rather it is assumed the fetus is not growing at the expected rate. 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. Research shows that routine obstetric ultrasound before 24 weeks gestational age can significantly reduce the risk of failing to recognize multiple gestations and can improve pregnancy dating to reduce the risk of for. Doppler sonography can be used to evaluate the pulsations in the fetal heart and bloods vessels for signs of abnormalities.

Internal validation with the actual date of delivery showed that ultrasound imaging provided reliable gestational age estimates.
