Which term is used for examination of body structures using a fluoroscope?

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

Answer: (B)

Fluoroscopy is a real-time imaging method that uses a fluoroscope to visualize internal body structures as X-rays pass through them. It often involves a contrast agent so you can watch movement or flow—such as swallowing, the passage of a catheter, or the placement of devices—while the image is displayed live on a monitor. This dynamic capability is what sets fluoroscopy apart from other imaging modalities: radiography provides a single static image, ultrasonography uses sound waves, and nuclear medicine relies on radioactive tracers with specialized cameras. Fluoroscopy therefore specifically describes examination with a fluoroscope to observe moving structures or functions in real time, though it does involve ionizing radiation and is used carefully to minimize exposure.
