Fluoroscopy is a medical imaging technique that allows doctors to see real-time moving images of the inside of the body. It uses a special type of X-ray technology to create a continuous stream of images, which can help in diagnosing and guiding various procedures. This method is often used to examine the digestive system, joints, and blood vessels. During a fluoroscopy exam, a patient may be asked to swallow a contrast agent, which helps highlight specific areas in the body. The images produced can show how organs function and can assist in planning treatments or surgeries, making it a valuable tool in modern medicine.
