What is the procedure of a fluoroscopy exam?

Fluoroscopy is a specific imaging technique that utilizes continuous X-ray technology to visualize movement inside the body in real-time. This method allows healthcare providers to observe the dynamics of various bodily functions, such as swallowing, the movement of joints, or the passage of contrast material through the gastrointestinal tract. The continuous nature of the X-ray imaging provides a live view, which is particularly useful for guiding certain procedures, diagnosing functional disorders, and evaluating how various organs and systems operate during activity.

In contrast, the other options describe different imaging modalities. Static images are typical of conventional radiography or X-rays, where individual pictures of structured anatomy are taken rather than a continuous stream. The use of sound waves for diagnostic purposes pertains to ultrasound imaging, which operates on a completely different principle. Finally, multiple cross-sectional scans are characteristic of computed tomography (CT) imaging, which does not provide live motion but rather detailed slices of anatomy. Each of these methodologies serves distinct purposes, but fluoroscopy is unique in its ability to demonstrate real-time function and movement.
