Question

Quizplus · Accepted Answer

Measuring the movements of protons in a magnetic field is the principle behind magnetic resonance imaging (MRI). Computed tomography uses X-rays, ultrasound scanning uses high-frequency sound waves, radionuclide scanning uses a small amount of radioactive material, and amniocentesis is a medical procedure to collect amniotic fluid for testing.
