fluoroskopie

Fluoroskopie is a medical imaging technique that uses continuous X-ray beams to produce real-time moving images of the internal structures of a patient’s body. The term derives from the Latin words "fluere," meaning "to flow," and Greek "skopé," meaning "watching" or "viewing." This technique allows physicians to observe the functioning of organs, visualize the positioning of medical devices, or guide certain diagnostic and therapeutic procedures.

During fluoroscopy, an X-ray source and a fluorescent screen or digital detector are positioned opposite each other. The X-ray beam passes through the patient's body, and the resulting images are displayed on a monitor in real-time. To reduce radiation exposure, modern systems often use digital detectors and pulsed X-ray sources. The procedure is commonly used in cardiology, gastroenterology, orthopedics, and radiology for applications such as angiography, barium swallow studies, catheter placements, and joint injections.

Safety considerations are paramount, as fluoroscopy involves exposure to ionizing radiation. Techniques to minimize dose include limiting exposure time, using protective shielding, and adopting dose-saving technologies.

Despite its benefits, fluoroscopy has limitations, including the potential risks associated with radiation exposure and the need for skilled operators. Advances in digital imaging and radiation safety continue to enhance its effectiveness and safety profile.

Overall, fluoroscopy remains a valuable diagnostic and interventional tool in modern medicine, aiding in accurate diagnosis, treatment planning, and execution of various procedures with real-time visualization.
