Question

Quizplus · Accepted Answer

Ultrasound uses high-frequency waves to create images of the fetus in-utero, allowing doctors to examine the fetus and monitor its development. Amniocentesis and chorionic villus sampling are invasive tests that involve extracting genetic material from the fetus and carry higher risks than ultrasound. Alpha-fetoprotein is a blood test that screens for certain abnormalities in the fetus, but it does not provide detailed images of the fetus like ultrasound.
