D)radionuclide scanning
E)amniocentesis

Question

Quizplus · Accepted Answer

Ultrasound scanning is a safe non-invasive imaging technique that uses high frequency sound waves to create an image of the developing fetus in the uterus during pregnancy. Computed tomography, magnetic resonance imaging, and radionuclide scanning are all invasive imaging techniques that use radiation or contrast agents that may pose risks to the developing fetus. Amniocentesis is a diagnostic test that involves inserting a needle through the mother's abdomen to collect a sample of the amniotic fluid surrounding the fetus and is used primarily for genetic testing, not imaging.
