Describe any two prenatal diagnostic procedures that can be used to diagnose structural abnormalities in the fetus.
What will be an ideal response?
Students' answers may vary.
Following are two of the less invasive types of prenatal tests:Ultrasound sonography: Ultrasound sonography is a prenatal medical procedure in which high-frequency sound waves are directed into the pregnant woman's abdomen. The echo from the sounds is transformed into a visual representation of the fetus's inner structures. This technique can detect many structural abnormalities in the fetus, like microcephaly.
Fetal MRI: This procedure uses a powerful magnet and radio images to generate detailed images of the body's organs and structure. It provides more detailed images than ultrasound sonography. Among the fetal malformations that fetal MRI may be able to detect better than ultrasound sonography are certain abnormalities of the central nervous system, chest, gastrointestinal tract, genital/urinary system, and placenta.
