Röntgenfluoroszkópia

Röntgenfluoroszkópia, often referred to as fluoroscopy, is a medical imaging technique that uses X-rays to obtain real-time moving images of the internal structures of a patient. Unlike a standard X-ray, which captures a single static image, fluoroscopy allows physicians to visualize the movement of organs, blood flow, and the passage of contrast agents through the body. This dynamic imaging capability is crucial for a variety of diagnostic and interventional procedures.

The process involves an X-ray source that passes a continuous beam of X-rays through the patient. These X-rays are then detected by an image intensifier or a flat-panel detector, which converts them into a visible image displayed on a monitor. This allows the radiologist or clinician to observe the internal anatomy in motion. Contrast agents, such as barium or iodine-based substances, are frequently administered to highlight specific structures or processes, such as the gastrointestinal tract, blood vessels, or urinary system. Fluoroscopy is employed in procedures like barium swallows, cardiac catheterization, angiography, and orthopedic interventions. While highly beneficial, the use of X-rays necessitates careful consideration of radiation exposure to both the patient and the medical staff.
