Yes, Fetal Alcohol Syndrome (FAS) can be seen on ultrasound. Ultrasound imaging is a noninvasive method of assessing fetal health and development. It uses high-frequency sound waves to generate images of the baby's internal organs, bones, and other structures. During an ultrasound, a technician will look for certain physical features that can indicate FAS. These features include a thin upper lip, small eyes, and an unusually small head circumference. Other signs of FAS, such as heart and skeletal abnormalities, can also be seen on an ultrasound. Additionally, the technician may be able to detect an enlarged space between the nose and upper lip, which is an indication of FAS.
While ultrasound imaging can be helpful in diagnosing FAS, it is not always definitive. The only way to confirm a diagnosis of FAS is through a blood test. Therefore, if a technician suspects FAS based on the ultrasound results, it is important to follow up with additional testing.
Overall, ultrasound is a useful tool for detecting FAS, but it is not a definitive diagnosis. Therefore, it is important to follow up with further testing if FAS is suspected.
