What is fluoroscopy primarily used for in medical imaging?

Fluoroscopy is primarily utilized in medical imaging to enable the visualization of body parts in motion. This imaging technique provides real-time images, allowing physicians to observe the function of organs and systems as they operate. For instance, fluoroscopy is commonly used in procedures such as watching the movement of the gastrointestinal tract, guiding joint injections, or observing the flow of contrast material through blood vessels or the urinary system.

The capability to see dynamic processes is essential in many areas of diagnostics and interventions, such as during catheter placements, barium swallow studies, and other functional imaging assessments. This real-time aspect distinguishes fluoroscopy from static imaging methods that provide a snapshot of anatomy without motion.
