What radiologic diagnostic procedure is used to evaluate fetal development?

Ultrasound is the preferred radiologic diagnostic procedure for evaluating fetal development due to its safety and effectiveness. It utilizes high-frequency sound waves to produce images of the developing fetus, allowing healthcare providers to monitor growth, check for anatomical abnormalities, and assess the overall health of the fetus in utero.

This method is particularly advantageous because it does not involve ionizing radiation, making it safe for both the mother and the fetus. Ultrasound can provide real-time imaging and is a non-invasive procedure, which makes it ideal for monitoring ongoing fetal development throughout pregnancy.

While X-rays, CT scans, and MRIs can produce detailed images, they are not commonly used for fetal evaluation due to either the exposure to radiation or the complexity and expense associated with these procedures. X-rays, for instance, use ionizing radiation, which poses risks during pregnancy. CT scans involve higher radiation doses, and MRIs, while safe in most cases, are less accessible and more costly compared to ultrasound.
