Obstetric Scans, or Prenatal Ultrasound, also known as Obstetric Ultrasound, are the application of medical ultrasonography during pregnancy. Sound waves are used to provide visual images of the developing foetus or embryo in the uterus in real time (womb). Since the procedure can provide a variety of information about the mother's health, the timing and progress of the pregnancy, and the health and development of the embryo or foetus, it is a common part of prenatal treatment in many countries.

Before Obstetrics Scans

There is very little preparation needed for a Transvaginal or Transabdominal Ultrasound. For Obstetric Ultrasounds performed after 18 weeks of pregnancy, some physicians urge their patients to arrive with a full bladder. The patient is instructed to empty the bladder by urinating right before the transvaginal scan. In addition to easing discomfort, this causes the bladder to collapse, improving the visibility of the pelvic organs.

During Obstetrics Scans

  • The radiologist applies a small amount of gel to the area to examine and place a transducer.
  • Sound waves can bounce back and forth between the transducer and the area being studied, thanks to the gel. On a television monitor, the ultrasound image is instantly visible.

FAQ's

Your doctor might recommend an Obstetric Scan to:

  • Verify the implantation, fertilisation, and existence of an embryo 
  • Determine if the pregnancy is one or multiple 
  • Determine the age and due date of the foetus
  • Assess the placenta and foetus's orientation concerning the delivery canal
  • Verify the foetus's surrounding amniotic fluid volume
  • Track the growth of the foetus
  • Examine for anomalies, inherited diseases, and congenital impairments

Obstetric Scans are indicated during: 

  • Early pregnancy or 8–11 week Dating Scan
  • Scan for nuchal translucency (11–14 weeks)
  • Early scan for anomalies (14–18 weeks)
  • Scan for foetal anomalies (19–23 weeks)
  • Foetal well-being or Growth scan (24–42 weeks)

The different types of Obstetric Scans are:

  • Dating Scan
  • First-Trimester Combined Screening (FTS)
  • Nuchal Translucency (NT)
  • Anatomy Scan
  • Biophysical Profile (BPP)
  • Complete Series

We ask that you have a full bladder before your ultrasound because this improves the ultrasound waves' ability to penetrate the body and produce a sharper image and more accurate diagnosis. Tell us, nevertheless, if your bladder feels overfull. To help you feel more comfortable, your scan room has attached washrooms where you can relieve yourself.

A regular Ultrasound should be carried out at 10 to 13 weeks of the gestational period if there are no alarming symptoms. This is to accurately identify the gestational period, assess viability, and count the number of foetuses. However, an emergency Pelvic Ultrasound needs to be carried out to rule out ectopic pregnancy if a woman with a positive pregnancy test exhibits worrisome signs such as pelvic or abdominal pain or vaginal bleeding.

If intrauterine pregnancy is identified, further assessment should include foetal heart rate, the amount of amniotic fluid, foetal movement, and the placenta. In cases of traumatic injury in females with confirmed or estimated pregnancy greater than 20 weeks gestation, OBGYN expert consultation should be sought as soon as possible, and a Transabdominal Ultrasound must be performed to evaluate foetal well-being as soon as the mother is stabilised.

Transvaginal Ultrasound may be somewhat contraindicated late in a term pregnancy or in high-risk pregnancies. However, the only absolute contraindication to Transabdominal and  Transvaginal Ultrasound is patient refusal. Transvaginal Ultrasonography is usually safe when the placenta is not disturbed.

Benefits associated with the scans are:

  • The majority of ultrasonic scanning doesn't require needlesticks or injections.
  • An ultrasound examination is not painful, although occasionally, it might be uncomfortable.
  • Compared to most other imaging techniques, ultrasound is less expensive, more accessible, and simple to use.
  • Since ultrasound imaging doesn't involve radiation, it is incredibly safe.
  • Soft tissues that are difficult to see on X-ray pictures can be seen using ultrasound scanning.
  • The recommended imaging modality for diagnosing and tracking pregnant patients and their foetuses is ultrasound. 
  • For almost 40 years, ultrasound has been used to assess pregnancy, and there is no proof that the patient, embryo, or foetus has suffered any harm as a result. However, ultrasonography should only be used when it is medically necessary.
  • Ultrasound allows the doctor to see inside the uterus and provides much information about the pregnancy.

All foetal abnormalities cannot be detected by Obstetric Ultrasonography. Therefore, in cases where a pregnant woman has laboratory or clinical suspicions of a possible abnormality, she maybe referred by her primary care physician to a perinatologist, an obstetrician who specialises in high-risk pregnancies, or she may need to undergo non-radiologic testing such as a blood test, Amniocentesis (the evaluation of fluid taken from the sac surrounding the foetus), or chorionic villus sampling (for the evaluation of placental tissue). 

 The accuracy of an ultrasound in determining due dates declines with increasing pregnancy. Within the range of 18 to 28 weeks of gestation, the error margin rises to two weeks. The ultrasound's estimated due date after 28 weeks may be incorrect by three weeks or more.
