Ultrasound imaging is also called

• A. Radiography
• B. Ultrasound scanning or Sonography
• C. Computed Tomography
• D. Magnetic Resonance Imaging

Answer: (D)

Ultrasound imaging is also called ultrasound scanning or sonography. This terminology comes from the use of high-frequency sound waves to create images of the body. A transducer emits sound waves and then captures the echoes that bounce back, turning them into real-time pictures. The name “sonography” uses the root sono- meaning sound, reflecting the modality’s reliance on sound waves rather than radiation or magnetic fields. The other options refer to different imaging methods: radiography uses X-rays, computed tomography builds images from rotating X-ray data, and magnetic resonance imaging uses magnetic fields and radiofrequency pulses. So the accurate term for ultrasound imaging is ultrasound scanning or sonography.
