What Is a Viability Scan and Why Is It Important in Early Pregnancy?

Introduction

A viability scan is an early ultrasound test during pregnancy. It helps check if the pregnancy is healthy and developing as expected. Many parents feel anxious in the first weeks. However, a viability scan can offer reassurance. This scan is important because it helps doctors confirm the baby’s heartbeat and growth. It also helps detect any early problems. In this blog, you will learn what a viability scan is, why it is done, and what to expect during the process.

What is a Viability Scan?

A viability scan is a simple ultrasound test. Doctors use it to check if a pregnancy is progressing normally. Usually, this scan uses sound waves to create images of the womb. These images show the baby’s heartbeat, size, and position. Most often, the scan is done through the vagina (transvaginal scan) in early pregnancy. Sometimes, it is done on the belly (transabdominal scan). The scan is painless and safe for both mother and baby.

Why is a Viability Scan Done?

Doctors recommend a viability scan for several reasons. For example, it helps confirm a healthy pregnancy. It also helps find out if there are any problems early on. Common reasons for a viability scan include:

  • Confirming the presence of a baby’s heartbeat
  • Checking the baby’s growth and age
  • Finding out if the pregnancy is inside the womb
  • Detecting multiple pregnancies (twins or more)
  • Investigating pain or bleeding in early pregnancy
  • Checking for signs of miscarriage or ectopic pregnancy

    • Because early pregnancy can be uncertain, a viability scan gives important answers.

    When is a Viability Scan Performed?

    Usually, a viability scan is done between 6 and 10 weeks of pregnancy. Before 6 weeks, it may be too early to see the heartbeat. However, if you have pain or bleeding, your doctor may suggest an earlier scan. Sometimes, women with a history of miscarriage or fertility treatment may need a scan sooner. Your doctor will decide the best time based on your health and symptoms.

    How is a Viability Scan Performed?

    First, the doctor will explain the procedure. In most cases, you do not need special preparation. However, you may be asked to drink water to fill your bladder. This can help get clearer images. During the scan:

  • You will lie down on an exam table
  • A gel is applied to your lower belly or a small probe is gently placed in the vagina
  • The doctor moves the probe to get images of the womb and baby
  • The scan usually takes about 10 to 15 minutes

    • After the scan, you can return to normal activities right away. Most women find the scan comfortable, though some may feel mild pressure.

    What Does a Viability Scan Show?

    A viability scan gives important information about your pregnancy. For instance, it can show:

  • Presence of a baby’s heartbeat
  • Number of babies (single or twins)
  • Baby’s size and age
  • Location of the pregnancy (inside the womb)
  • Signs of problems, such as miscarriage or ectopic pregnancy

    • If the scan shows a healthy heartbeat and growth, it is a good sign. However, if there are concerns, your doctor will explain the next steps. Sometimes, a repeat scan is needed to confirm results.

    Risks and Safety

    Viability scans are very safe. They use sound waves, not radiation. According to the World Health Organization (WHO), ultrasound scans do not harm the mother or baby. Most women do not feel any pain. Rarely, some may feel mild discomfort during a transvaginal scan. However, there are no known long-term risks.

    Frequently Asked Questions

  • Is a viability scan painful? Most women feel no pain. Some may feel mild pressure during a transvaginal scan.
  • Do I need to prepare for the scan? Often, you may be asked to drink water before the scan. Your doctor will give you instructions.
  • Can a viability scan detect twins? Yes, the scan can show if you are carrying more than one baby.
  • What if no heartbeat is seen? Sometimes, it may be too early. Your doctor may suggest a repeat scan in a week.

    • Conclusion and Next Steps

    In summary, a viability scan is a safe and helpful test in early pregnancy. It checks the baby’s heartbeat, growth, and location. The scan can also detect early problems. If you have questions or concerns about your pregnancy, consult a radiologist or your healthcare provider for personalized advice. Early care can help ensure a healthy pregnancy journey.
