Anomaly Scan Insights: Advanced Detection of Foetal Development and Structural Variations

The journey of pregnancy is special for every mother. It is filled with joy, anticipation, and also a fair share of worries. Each mother wants her baby to be born healthy and remain healthy as well. In this case, medical science plays a key role indeed. One of the most significant aspects of pregnancy care is the anomaly scan. It is also known as the mid-pregnancy ultrasound or level 2 scan. 

The scan is typically performed between the 18th and 22nd week of pregnancy. This scan is not just a routine check-up. It is all about checking the development of the baby and detecting any structural variations or potential concerns early. 

Here, in this article, we will talk about this scan, its importance and how it empowers parents and doctors to make informed decisions.

What Is an Anomaly Scan?

An ultrasound scan that involves a closer look at the baby inside the womb is called an anomaly scan. This test is much more detailed as compared to the early pregnancy scans; one can be sure and can hear the heartbeat.

The purpose is to:

• Examine the anatomy of the baby.
• Search structural variations or abnormalities.
• Examine the placenta, the amniotic fluid, and the umbilical cord.
• Observes growth trends and general growth.

It is totally harmless, non-invasive and painless. The process resembles that of a normal ultrasound. A sticky gel is put on the abdomen, and the sonographer then moves the probe to get the baby images.

Why Is It Called An Anomaly Scan?

The term “anomaly” used in the context here means structural variations or deviations in the developing foetus. These can be minor, major and occasionally even temporary variations. Their early detection is very important because it would enable the healthcare professionals to arrange the appropriate medical treatment and train parents about the future.

What Is The Checklist?

The anomaly scan is detailed and takes time, often around 30 to 45 minutes. The sonographer examines each part of the baby systematically.

Organs and Structures Checked:

1. Brain and Skull
   
   
   • Shape, size, and presence of structures like ventricles and cerebellum.
     
     
   • Detection of neural tube defects such as spina bifida.
     
     
2. Face
   
   
   • Formation of the eyes, nose, lips, and jaw.
     
     
   • Screening for cleft lip or palate.
     
     
3. Heart
   
   
   • Position and chambers of the heart.
     
     
   • Flow of blood through major vessels.
     
     
   • Detection of congenital heart defects.
     
     
4. Spine
   
   
   • Alignment and completeness.
     
     
   • Screening for spinal abnormalities.
     
     
5. Abdomen
   
   
   • Stomach, kidneys, liver, and bladder.
     
     
   • Location of organs to rule out abnormalities.
     
     
6. Limbs
   
   
   • Arms, legs, hands, and feet.
     
     
   • Measurements of bone length to ensure proper growth.
     
     
7. Placenta and Amniotic Fluid
   
   
   • Position of the placenta (checking for placenta previa).
     
     
   • Volume of amniotic fluid to ensure a safe environment for the baby.

What Conditions Can It Detect?

Not all conditions can be detected, but many significant variations can be identified. These include:

• Neural tube defects (spina bifida, anencephaly).
  
  
• Heart defects.
  
  
• Cleft lip and palate.
  
  
• Abdominal wall defects (gastroschisis, exomphalos).
  
  
• Kidney abnormalities.
  
  
• Limb malformations.
  
  
• Growth restrictions.
  
  

In some cases, the scan may also reveal soft markers that suggest a higher chance of chromosomal conditions such as Down syndrome. While the scan cannot confirm such conditions, it can highlight the need for further testing.

What Are The Consequences In Case Of An Anomaly?

In case the sonographer observes an abnormality, additional measures might involve:

• Confirmation by repeated ultrasound.
• The echocardiography of the heart in foetuses.
• Genetic screening such as amniocentesis.
• A clear picture in some cases with an MRI scan.

It is not only detection, but it is also planning. Early diagnosis also aids the doctors to be ready to write the appropriate treatment, intervention or delivery in a specialised medical facility in case they are required.

The Importance of Anomaly Scan

Anomaly scan is one of the most useful aids in contemporary prenatal practice. Its importance lies in:

• Timely diagnosis of conditions.
• Enlightened decision-making by parents and doctors.
• Healthier pregnancies through planning.
• Mind peace among parents when all looks normal.

Although no scan can ensure that a baby is born without health problems, the level 2 scan is very likely to detect serious concerns prior to birth.

Preparing for the Scan

Parents often ask if they need to prepare for the scan. The answer is simple: very little.

• Wear comfortable clothing.
  
  
• Drink some water beforehand, as a slightly full bladder may help get clearer images.
  
  
• Be prepared for the scan to take time, as every detail needs to be checked.
