Accurate dating pregnancy ultrasound

Performing the transvaginal ultrasound usually causes less discomfort than a pap smear. Your privacy will always be respected during your ultrasound, especially the transvaginal examination.You will have a large towel covering your lower body, in addition to wearing a gown during the transvaginal ultrasound.Transvaginal ultrasound usually produces better and clearer images of the female pelvic organs including the developing pregnancy, because the ultrasound probe lies closer to these structures.The transvaginal ultrasound probe is thin, about 2cm diameter.However, in the early pregnancy, the developing embryo is very small (at 6 weeks gestation, the baby is only 5-9mm long) and a transvaginal ultrasound may be required to get a better image of the baby.Transvaginal ultrasound is safe and commonly performed during all stages of pregnancy, including the first trimester. Transabdominal ultrasound involves scanning through your lower abdomen.Ultrasound uses high-frequency sound waves to create images of the inside of the body. It is safe, painless and relatively quick test that usually takes around 30 minutes.The technician will put a warm gel on your abdomen and use a scanning device to get the ultrasound images.

The most accurate way to “date” your pregnancy is with an early ultrasound.As the name suggests, this type of ultrasound looks at your baby’s anatomy.The number of fetuses, gestational age, and location of the placenta will be assessed.The Society of Obstetricians and Gynaecologists of Canada recommends that all women have two ultrasounds: one “dating” ultrasound at 11-14 weeks and one “anatomic” ultrasound between 18-20 weeks.See below for descriptions of the information gathered from these two types of ultrasounds.
