Which imaging modality is also called X-ray imaging?

• A. Radiography
• B. Fluoroscopy
• C. Nuclear medicine
• D. Barium

Answer: (A)

X-ray imaging is the use of ionizing radiation to create images of internal structures, typically as a single still picture. The modality that is commonly called X-ray imaging is radiography, which produces a static radiograph to visualize bones, lungs, and other tissues. Fluoroscopy also uses X-rays but provides continuous, real-time video images to observe movement, so it’s a dynamic form rather than a single still image. Nuclear medicine images are obtained with radiotracers to assess function, not just anatomy, and barium is a contrast agent used with X-ray techniques to outline the GI tract rather than a standalone imaging modality.
