Which imaging technique is commonly used to monitor fetal development?

• A. Ultrasound
• B. X-ray
• C. CT scan
• D. MRI

Answer: (A)

For monitoring fetal development, the best imaging choice is ultrasound. It uses high-frequency sound waves to create live images of the fetus inside the uterus, so clinicians can watch growth, check the heartbeat, observe movements, and assess key features like placental position and amniotic fluid. Because it does not involve ionizing radiation, it can be used repeatedly throughout pregnancy without radiation risk, making it ideal for ongoing monitoring and timely decisions if any concerns arise. Ultrasound is also widely available and relatively affordable, which further supports its role as the standard tool for routine prenatal checks. X-ray and CT scans use ionizing radiation, which can harm a developing fetus, so they are avoided during pregnancy unless absolutely necessary. MRI uses strong magnetic fields and is safe in pregnancy but is more costly, takes longer, and is not the routine method for regular fetal monitoring, though it may be used for specific, detailed investigations when needed.
