What Are Obstetric Ultrasounds Or Sonograms?

Obstetric Ultrasound is the use of ultrasound scans in pregnancy. Since its introduction in the late 1950’s ultrasonography has become a very useful diagnostic tool in Obstetrics.

A pregnancy ultrasound is a method of seeing the fetus and female pelvic organs during pregnancy. The ultrasound machine sends out high-frequency sound waves. These waves bounce off body structures to create a picture.

Why Is Ultrasound Used During A Pregnancy?

Ultrasound scans are considered to be a safe, non-invasive, accurate and cost-effective investigation in the fetus. It has progressively become an indispensable obstetric tool and plays an important role in the care of every pregnant woman.   Some physicians order an ultrasound when an abnormality is suspected, while others advocate screening ultrasounds. You should consult your health care provider to determine the most appropriate scanning schedule for you.

How Is An Ultrasound Or Sonogram Performed?

You will lie down for the procedure. A clear, water-based conducting gel will be applied to your skin over your abdomen and pelvis. The gel helps transmit sound waves. A hand-held probe is then moved over the area.

Another method is performed with a specially designed probe placed in the vagina of the patient (transvaginal ultrasound scanning). This technique often complements conventional ultrasound techniques by providing better detail. Consult your health care provider to determine which technique is most appropriate for you.

Are Ultrasounds And Sonograms Safe?

There is no documented effect on patients and their fetuses with the use of current ultrasound techniques. Unlike X-rays, ionizing radiation is not present.
