Obstetric Ultrasonography To Gather Vital Information During Pregnancy

Obstetric Ultrasonography is the application of medical ultrasonography to obstetrics. This imaging technique is used to visualize the embryo or fetus within a woman's uterus. This procedure is considered to be a part of prenatal care since it provides wealth of information regarding the health of the mother and of the fetus, as well as regarding the progress of the pregnancy.

Obstetric Ultrasonography Is Conducted To Gather Information On The Following:

  • To determine the presence of a living embryo/fetus
  • To estimate the age of the pregnancy
  • For diagnosis of congenital abnormalities of the fetus
  • To evaluate the position of the fetus
  • To evaluate the position of the placenta
  • To determine if there are multiple pregnancies
  • To determine the amount of amniotic fluid around the baby
  • To check for opening or shortening of the cervix or mouth of the womb.
  • To assess fetal growth
  • To assess fetal well-being
Using Obstetric Ultrasonography, the gestational sac can be visualized within four and a half weeks of gestation and the embryo can be measured by five and a half weeks. This imaging technique is also used to the gestational age. The sex of the baby can also be determined by the sixteenth week. An important application of this technique is in the assessment of the cervix in women at risk for premature birth.

During the procedure, a transducer is placed on the abdomen of the pregnant women. The transducer emits high frequency sound waves to capture images of the embryo or fetus in uterus.
