Introduction
To ensure healthy fetal development, pregnant women should undergo regular prenatal checkups during pregnancy, including ultrasound examinations. In daily life, pregnant women should maintain good lifestyle habits, such as eating a balanced diet, engaging in moderate exercise, and avoiding exposure to harmful substances, all of which help reduce the risk of congenital abnormalities in the fetus, such as neural tube defects.
In general, open neural tube defects can be detected by ultrasound. The detailed analysis is as follows:
Open neural tube defects, such as spina bifida and anencephaly, result from incomplete closure of the neural tube during fetal development. These defects gradually exhibit distinct morphological features as the fetus develops. Ultrasound is a non-invasive, real-time, and highly visual imaging technique that clearly displays the internal structures and morphology of the fetus. During the mid-pregnancy anomaly scan, ultrasound can accurately assess the continuity and integrity of the fetal spine, as well as evaluate whether the shape and structure of the fetal skull are normal. Therefore, for congenital malformations like open neural tube defects that involve obvious morphological abnormalities, ultrasound is usually able to detect them effectively.
To ensure healthy fetal development, pregnant women should undergo regular prenatal examinations, including ultrasound scans. Additionally, maintaining healthy lifestyle habits—such as eating a balanced diet, engaging in moderate exercise, and avoiding exposure to harmful substances—can help reduce the risk of congenital abnormalities, including neural tube defects.
