An imaging method that uses high-frequency sound waves to produce an internal image to assist in women’s health care during their pregnancy. It provide a view of the reproductive system to be assesed by our renowned OB-GYN Sonologists.

Here are services available from the unit:


“Transvaginal” means “through the vagina.”

A diagnostic tool where the ultrasound probe is inserted through the vaginal canal condition. Where a transvaginal ultrasound might be necessary for:

  • an abnormal pelvic or abdominal exam
  • unexplained vaginal bleeding
  • pelvic pain
  • Infertility

Transvaginal ultrasound during pregnancy intends to:

  • check for the location and monitor the heartbeat of the fetus
  • check the cervix for any changes that could lead to complications such as miscarriage or premature delivery
  • examine the placenta for abnormalities
  • identify the source of any abnormal bleeding
  • diagnose a possible miscarriage
  • confirm an early pregnancy

UA transvaginal ultrasound helps diagnose multiple conditions, including:

  • Routine pregnancy
  • Ectopic pregnancy
  • Miscarriage
  • Placenta previa (a low-lying placenta during pregnancy that may warrant medical intervention)
  • Ovarian cysts
  • myoma uterine
  • Incompetent cervix
  • Endometrial polyp or mass


Transrectal ultrasound is performed using a transvaginal probe, which is lubricated and slowly advanced into the rectum. The technique used was similar to that of transvaginal ultrasound and it is used when transvaginal ultrasound is not possible (i.e. on patient with no sexual contact).


A transabdominal or pelvic ultrasound is a diagnostic tool that uses sound waves evaluate organs within the pelvis.

This diagnostic tool is mostly used during pregnancy, is also used to evaluate the following organs:

  • Cervix
  • Fallopian tubes
  • Ovaries
  • Uterus
  • Vagina
  • Bladder

Congenital Anomaly Scan

Screening for congenital abnormalities has become a routine part of pregnancy care.

Normal human development is hugely complex and while most babies are born without birth defects, the unfortunate reality is that there is always a risk of abnormal development, regardless of a mothers or father's age, family or personal history, or lifestyle.

Congenital abnormalities and birth defects affect 2-3% of all pregnancies, with most of these being minor. A small minority of babies have major birth defects.

Two pregnancy ultrasound scans are used to detect the vast majority of serious birth defects:

  • 12 week nuchal translucency pregnancy scan. This 'first trimester combined screen' is carried out between week 11 and 14.
  • 20 week anatomy and anomaly pregnancy scan this 'second trimester scan' is carried out between 18 and 22 weeks.

Biophysical Scoring

This test combines fetal heart rate monitoring (nonstress test) and fetal ultrasound to evaluate a baby's heart rate, breathing, movements, muscle tone and amniotic fluid level. The nonstress test and ultrasound measurements are then each given a score based on whether certain criteria are met.

A biophysical profile (BPP) test evaluates the health of your baby (fetus) during pregnancy. A BPP test may include a nonstress test with electronic fetal heart monitoring and a fetal ultrasound.

The BPP examines your baby's heart rate, muscle tone, movement, breathing, and the amount of amniotic fluid around your baby.

Typically, a biophysical profile is recommended for women at high risk for problems that could lead to complications or pregnancy loss. The test is usually done after week 32 of pregnancy, but can be done when your pregnancy is far enough along for delivery to be considered — usually after week 24.

A low score on a biophysical profile might indicate that you and your baby need further testing. In some cases, early or immediate delivery might be recommended.


Doppler velocimetry is a way to make sure that your baby is getting a healthy supply of blood. You may need it if earlier tests showed that your baby could be having problems. Maybe your baby is growing slowly or has anemia.

You may also need the test if you have preeclampsia or have a low level of amniotic fluid.

Doppler velocimetry is different from a standard Doppler that checks your baby's heartbeat.

Doppler velocimetry uses ultrasound to check blood flow in the umbilical cord or between the uterus and the placenta. If the blood supply is restricted, your baby can't get enough nutrients and oxygen.

2D Ultrasound

This type of ultrasound produces outlines and flat-looking images which can be used to view the baby’s internal organs and how your baby is developing.

It advisable to take this test during the 2nd trimester or between 18-22 weeks or pregnancy to check the baby’s overall health including:

  • Heart rate
  • Sex Gender
  • Congenital abnormalities
  • Signs of Down Syndrome
  • Baby’s position in the uterus
  • Any potential internal issues

3D / 4D Ultrasound

3D ultrasound can clearly show the internal organs of a developing fetus. This can also be used to diagnose facial or skeletal abnormality.

While the 4D on the other hand is used if the patient would like to be continuously updated on the fetus’ fluid-like moving image.
