Video fluoroscopy is a medical imaging technique that uses X-rays to create real-time moving images of internal structures. It allows healthcare professionals to observe the function of organs and systems, particularly in the gastrointestinal tract, during various activities such as swallowing or movement. This procedure involves the use of a special camera that captures the X-ray images and displays them on a monitor. Radiologists often use video fluoroscopy to diagnose conditions, assess the effectiveness of treatments, and guide certain medical procedures, providing valuable insights into a patient's health.
