Is The 20 Week Anatomy Scan Internal Or External?

When it comes to prenatal care, one of the crucial milestones during pregnancy is the anatomy scan, also known as the level 2 ultrasound, which is typically performed around the 20-week mark. This scan is vital as it provides detailed information about the baby’s development, growth, and overall health. But a common question that often arises among expectant parents is whether the 20-week anatomy scan is internal or external.

External Anatomy Scan

During the 20-week anatomy scan, the procedure is usually conducted externally using an external transducer, also known as an ultrasound wand. The external transducer emits high-frequency sound waves that penetrate the abdomen to create images of the baby and the uterus. Your sonographer will apply a warm gel on your belly and move the wand to obtain measurements and images of the baby.

There are several benefits to having an external anatomy scan, including it being non-invasive and generally more comfortable for the mother. However, there are limitations to this approach, as it may not provide as much detailed information as an internal scan.

Internal Anatomy Scan

An internal anatomy scan, also known as a transvaginal ultrasound, may be recommended in certain cases where more detailed information is needed. This procedure involves inserting a probe into the vagina to get closer to the uterus and obtain clearer images of the baby. While internal scans may be more invasive, they can offer better visualization, especially in early pregnancy.

Although internal scans can provide more detailed images, they also have limitations such as being slightly uncomfortable for some women. It is essential to discuss with your healthcare provider whether an internal scan is necessary based on your specific circumstances.

Comparison between Internal and External Anatomy Scans

When comparing internal and external anatomy scans, there are significant differences in the procedure and the information obtained. Internal scans tend to offer clearer images, particularly in the early stages of pregnancy, while external scans are more commonly used and are less intrusive.

Factors influencing the choice between internal and external scans include the stage of pregnancy, the need for detailed information, and individual preferences. It is essential to communicate with your healthcare provider to determine the most suitable option for your anatomy scan.

Conclusion

In conclusion, the 20-week anatomy scan is typically performed externally using an ultrasound wand on the abdomen. However, in certain circumstances, an internal scan may be necessary to obtain detailed information about the baby’s development. Both internal and external scans have their advantages and limitations, and the choice between the two depends on various factors.

For pregnant individuals, it is crucial to attend the 20-week anatomy scan appointment as it plays a significant role in monitoring the baby’s health and ensuring a smooth pregnancy journey. Remember to discuss any concerns or questions with your healthcare provider to make informed decisions about your prenatal care.
