The viability scan, the first ultrasound performed in pregnancy as part of prenatal care, provides vital information about a fetus’s health, including growth and development. It is referred to as the “dating scan” because it helps to confirm that your pregnancy is progressing satisfactorily.

When can I have the Viability scan?

This scan of the first trimester is usually performed at around 7 weeks (between the 6th and 10th week), only by fetal medicine specialists.

What is the aim of the viability scan?

  • Assess for internal bleeding or any sign of complications
  • Confirm that a pregnancy is developing normally inside the uterus (intrauterine)
  • Check that the baby has a heartbeat
  • Determine the number of embryos
  • Detects whether the embryos share a common placenta in the case of a multiple pregnancy
  • Examine the uterus and the ovaries
  • Exclude the possibility of an ectopic pregnancy (outside the uterus) or an ectopic pregnancy in the scar of a previous cesarean section, which can cause serious complications
  • Identify potential issues, such as fibroids or ovarian cysts, and congenital abnormalities, such as a bicornuate uterus

How is the viability scan performed?

The sonographer passes a transducer across your belly. In very early pregnancies or when clearer images are needed, it may be placed in the vagina. The examination takes approximately 20 to 30 minutes.

 

Who should consider a viability scan?

A viability scan is recommended for:

  • Women who experienced bleeding, unusual pain, or other concerning symptoms
  • Women who faced miscarriages, including an ectopic pregnancy.
  • Women with a desire to ensure the healthy progression of their current pregnancy

 

What happens after the viability scan?

Nuchal Translucency (NT) scan, performed between 20 and 24 weeks of gestation, is the next step to ensure that your journey will be safe and comfort at any stage of your pregnancy and birth.
