Introduction
An anomaly scan, often referred to as a level 2 ultrasound, is a crucial mid-pregnancy imaging test designed to assess the health and development of your baby. Typically conducted between 18 and 20 weeks of pregnancy, this scan provides a detailed view of the fetus, checking for normal growth and identifying any potential defects. Commonly known as the morphology scan or 20-week scan, it also helps in evaluating the position of the amniotic fluid and placenta, offering vital insights into the baby’s well-being.
1.What is an anomaly scan (level 2 ultrasound)?
An anomaly scan, also called a level 2 ultrasound, is a mid-pregnancy scan that takes a closer look at your baby and uterus. In this scan, the sonographer can see if the baby is developing normally and will also check the position of the amniotic fluid around your baby. This scan is also called a morphology scan or a 20-week scan. The purpose of this scan is to check your baby’s health, and the gender may also be determined during it
2.What can an anomaly scan detect?
The main purpose of the anomaly scan is to make sure that the baby is growing well without any defects.
Baby’s heart the sonographer will check if the baby’s heart is developing and working properly.
Fetal kidneys the sonographer checks whether your fetus has two kidneys and whether the bladder is filling.
Head development The shape of the fetal head is also checked. Problems related to brain development, if any, are highlighted immediately. Development of the spine – The sonographer also checks whether the baby’s spine is developing properly and whether the skin on the back is covering it properly. Organ development The sonographer will also check if the baby’s organs are developing properly. Amniotic Fluid The sonographer will check to see if there is enough amniotic fluid around the baby to provide protection. Placenta The position of the placenta is checked during the anomaly scan. If your placenta is low in your uterus, your doctor will let you know.
3.When is an anomaly scan performed?
This scan is done to check for incontinence in the second trimester of pregnancy. It is usually done between 18 and 20 weeks of pregnancy. An ultrasound scan helps ensure that the baby’s growth is normal and that all vital organs are developing properly.
4.What do the anomaly scan results mean?
The results of this anomaly scan indicate the development of the baby in the womb and help determine the fetal growth graph. The results will either show that the fetus is developing correctly or the scan will show if there is a problem. In case of defects, your doctor will discuss corrective measures.
5.What defects does an anomaly scan detect?
Here are some of the defects that can be detected in anomaly scans: Although the scan is aimed at finding defects, it is not always easy to find the defect in the baby. For example, if there are problems with the abdominal wall, kidneys, organs or spine, there is a good chance that the scan will detect them. But, the chances of seeing defects in the heart, or assessing whether there is a hole in the muscle that separates the chest and abdomen, or detecting excess fluid in the brain are relatively low. If anything unusual is observed, the sonographer may refer the report to another person to confirm the observation and then discuss a plan of action.
6.Is an anomaly scan valid?
This mid-pregnancy ultrasound scan is very important because it can help determine fetal growth and early detection of fetal defects that may develop. Anomaly scans or anomaly scans give images; However, it is not always necessary that scans are 100% accurate and show accurate results all the time. This is because it is difficult to determine the defect in the baby, especially the defects of the vital organs. Abnormalities are often not easily visible in the scan. A sonographer may also need to scan the abdomen several times to get a clear picture of the baby. Usually, parents are also asked to give consent with the understanding that scan results may not be 100% accurate.
Conclusion
The anomaly scan is a key diagnostic tool in prenatal care, providing essential information about your baby’s development and detecting potential issues early. While it is highly informative, it’s important to remember that the scan is not always 100% accurate, and some defects may not be easily visible. If any abnormalities are detected, further evaluations may be needed. Understanding the purpose and scope of the anomaly scan can help you prepare for this important step in your pregnancy journey and ensure that any necessary follow-up actions are taken.
