Pregnancy Ultrasound

Pregnancy ultrasound can be used in several ways. It can measure the size of the fetus’s body parts, such as the head, which is useful in dating a pregnancy.  It can follow the growth of the fetus. It can produce a cross-sectional picture, or slice, of the fetal body. A slice through the fetal abdomen can show the size and location of the organs inside. A slice through the brain can identify the ventricles (fluid-filled cavities), providing information about their normality or enlargement {hydro-cephalus). Ultrasound can also be used to observe movements of fetal structures such as the beating of the heart, emptying of the bladder, movements of the chest, and sucking on the thumb.

History of Ultrasound

Ultrasound (sonography) is a diagnostic technology that has had a major impact on maternity care and medical practice in general. It originated during World War II when high-frequency sound waves were first used to detect enemy submarines. The echoes of sound wave beamed into the water were reflected back from any object encountered, to be heard by electronic sensors. Below are all the details of pregnancy ultrasound.  Not only this we have also done research to answer the common question of pregnancy ultrasound safety issue.

Purpose of pregnancy ultrasound

  1. Identifying an embryo or fetus to diagnose pregnancy.
  2. Monitoring the growth of the fetus.
  3. Determining whether a fetus has or has not been aborted.
  4. Verifying the existence of a tubal (ectopic) pregnancy.
  5. Identifying multiple pregnancies and fetal position.
  6. Identifying fetal abnormalities such as Meningomyelocele hydrocephalus and limb defects. More recently measuring the translucency of the fetal neck has proved useful in detecting Down syndrome. Some abnormalities are transient, occurring early in pregnancy and not later. A common transient abnormality is a small cyst (or cysts) within the brain known as a choroid plexus cyst. If the ultrasound is otherwise normal, these cysts may be significant in their rare association with trisomy.
  7. Locating the placenta and determining placental abnormalities.
  8. Measuring die amniotic fluid on hydramnios and oligohydramnios.
  9. Guiding needle insertion in amniocentesis, chorionic villus sampling, and fetal cord blood sampling.
  10. Measuring the fetal heart rate during prenatal visits stress and no stress and labor.
  11. Treating the fetus before birth.
  12. Measuring the pulsations of the fetal arteries in the umbilical cord as a test of fetal well-being.
  13. Estimating the weight of the fetus to assess the safety of a vaginal birth after a previous cesarean birth.

Safety During Pregnancy Ultrasound

The safety of ultrasound appears proven. To date there has been no evidence of fetal abnormalities related to its use, nor have changes been observed in living cells in tissue culture after exposure to the doses used in humans.

Although ultrasound examination is increasingly used in all pregnancies.  Existing studies of performing a single ultrasound test or two tests, one early and one late, in pregnancies at low risk for fetal abnormality have not shown that outcomes for babies were improved. The studies showed that such routine testing led to earlier identification of twins, revision of the expected date of delivery, and earlier detection of fetuses with congenital malformations. In the case of severe malformation, earlier detection allowed for earlier abortion as an option. However, these studies used less powerful equipment than is now available. If they were repeated with today’s technology and the increased knowledge we have of how to interpret ultrasound images.  It is likely that significant benefits would be identified. There is now a strong general consensus, even without a controlled study, that 3 weeks pregnant ultrasound should be routine.

The experience by parents-to-be of seeing ultrasound images of their babies has introduced a new graphic dimension into the fetal-parental relationship. New family albums often open with an ultrasound portrait. Ultrasound images of the fetus with a beating heart and moving limbs have also fueled the claim of opponents of abortion that a fetus is a person from the time of conception.
