Fluoroscopy is a medical imaging technique that uses X-rays to obtain real-time moving images of the interior of the body. It's similar to an X-ray "movie" and is often used during diagnostic and therapeutic procedures.
Key aspects of fluoroscopy include:
Real-time imaging: Unlike a static X-ray, fluoroscopy provides live, continuous images on a monitor, which allows healthcare providers to see the movement of internal structures and fluids.
Guidance for procedures: Fluoroscopy is often used to guide a variety of medical procedures. For example, it's used in angiography to visualize the flow of blood through blood vessels, in orthopedic surgery to guide the placement of implants, and in gastrointestinal studies to observe the movement of the digestive system.
Contrast agents: Sometimes, a contrast agent is used during fluoroscopy to make certain tissues or vessels more visible. This agent is usually swallowed or injected into the body and appears white on the fluoroscopy screen, highlighting organs like the intestines, blood vessels, or specific areas of the musculoskeletal system.
Low dose of radiation: Fluoroscopy uses a lower dose of radiation compared to other imaging techniques like CT scans. However, the duration of exposure can vary depending on the procedure.
Dynamic assessment: Fluoroscopy can assess the function of moving body parts, such as joints, muscles, and the heart, providing valuable information that cannot be obtained from static images.
Fluoroscopy is a versatile tool used in many areas of medicine. However, due to the use of radiation, its use is carefully considered and usually only performed when necessary. The benefits of obtaining crucial diagnostic or therapeutic information generally outweigh the risks associated with the small amount of radiation exposure.
