Obstetric ultrasound

   Ultrasound imaging, also called ultrasound scanning or sonography , involves the use of a small transducer (probe) and ultrasound gel to expose the body to high-frequency sound waves. Ultrasound is safe and painless, and produces pictures of the inside of the body using sound waves. Ultrasound examinations do not use ionizing radiation(as used in x-ray ). Because ultrasound images are captured in real-time, they can show the structure and movement of the body's internal organs, as well as blood flowing through blood vessels.

Ultrasound imaging is a noninvasive medical test that helps physicians diagnose and treat medical conditions.

Obstetrical ultrasound provides pictures of an embryo or fetus within a woman's uterus, as well as the mother's uterus and ovaries.

A Doppler ultrasound study may be part of an obstetrical ultrasound examination.

Doppler ultrasound is a special ultrasound technique that evaluates blood flow through a blood vessel, including the body's major arteries and veins in the abdomen, arms, legs and neck.

During an obstetrical ultrasound the examiner may evaluate blood flow in the umbilical cord or may, in some cases, assess blood flow in the fetus or placenta

Obstetrical ultrasound is a useful clinical test to:

  • establish the presence of a living embryo/fetus.

  • estimate the age of the pregnancy.

  • diagnose congenital abnormalities of the fetus.

  • evaluate the position of the fetus.

  • evaluate the position of the placenta.

  • determine if there are multiple pregnancies.

  • determine the amount of amniotic fluid around the baby.

  • check for opening or shortening of the cervix.

  • assess fetal growth.

  • assess fetal well-being.

We as some physicians also use 3-D ultrasound to image the fetus and determine if it is developing normally.
