What are the disadvantages of using ultrasound in pregnancies?

Ultrasound in pregnancies has several disadvantages, including the potential for misinterpretation of images, which can lead to unnecessary anxiety or inappropriate medical decisions. It may also provide limited information about certain fetal conditions, as it primarily assesses structural anatomy rather than functional aspects. Additionally, frequent exposure to ultrasound, although generally considered safe, raises concerns about potential effects on fetal development, although research in this area is ongoing. Finally, access to high-quality ultrasound technology may be limited in some regions, leading to inequalities in prenatal care.
