Description: Fluoroscopy is a medical imaging technique that uses X-rays to obtain real-time images of the inside of the body. Unlike conventional X-rays, which provide static images, fluoroscopy allows for the observation of the movement of internal organs and structures, which is essential for diagnosing and treating various conditions. This technique relies on the emission of X-rays that pass through the body and are captured by a detector, generating images on a screen. Fluoroscopy is particularly useful in procedures that require continuous visualization, such as gastrointestinal studies, where the passage of a contrast medium through the digestive tract can be observed. Additionally, it allows for the guidance of minimally invasive interventions, such as catheter placement or biopsy procedures. Its ability to provide dynamic images in real-time makes it a valuable tool in clinical practice, enhancing the accuracy of diagnoses and treatments.
History: Fluoroscopy was developed in the late 19th century, shortly after the discovery of X-rays by Wilhelm Conrad Röntgen in 1895. In 1896, French physician Pierre Curie used fluoroscopy to observe the movement of bones in real-time. Over the years, the technique was refined, incorporating technological improvements such as the use of fluorescent screens and digital detectors, which increased its effectiveness and safety. However, the use of fluoroscopy has also been associated with radiation exposure risks, leading to the implementation of safety measures and protocols to minimize the radiation dose received by patients.
Uses: Fluoroscopy is used in various medical applications, including studies of the gastrointestinal system, such as swallowing and intestinal transit. It is also employed in interventional procedures, such as stent placement, fluid aspiration, and image-guided biopsy. Additionally, it is useful in evaluating orthopedic issues, such as joint movement and bone alignment.
Examples: An example of fluoroscopy use is a swallowing study, where the passage of food through the esophagus is observed. Another case is the placement of a catheter in the heart, where fluoroscopy guides the physician to ensure the catheter is positioned correctly. It is also used in evaluating mobility issues in joints, such as in sports injuries.
