Fluoroskoppikuvaus

Fluoroskoppikuvaus, known in English 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 produces a single static image, fluoroscopy allows physicians to visualize the dynamic processes within the body, such as the movement of organs, blood flow, or the insertion of medical instruments.

The process involves an X-ray source and an X-ray detector positioned on opposite sides of the patient. The X-ray beam passes through the body, and the attenuated beam is captured by the detector, which converts the X-ray energy into visible light. This light is then amplified and displayed on a monitor, creating a continuous, live image.

Fluoroscopy is often used in conjunction with contrast agents, such as barium or iodine-based compounds. These agents are introduced into the body (e.g., swallowed for digestive tract imaging, injected into blood vessels) and enhance the visibility of specific organs or tissues on the fluoroscopic images.

Common applications of fluoroscopy include guiding procedures like cardiac catheterization, placing stents, performing barium swallows to examine the esophagus and stomach, and assisting in orthopedic surgeries. While valuable for its real-time imaging capabilities, fluoroscopy involves exposure to ionizing radiation, and the duration of the examination is carefully managed to minimize patient dose.
