Fluoroscopy is a medical imaging technique that uses X-rays to create real-time moving images of the inside of the body. It allows doctors to observe the function of organs and systems, such as the digestive tract or the heart, during procedures. This technique is often used for guiding interventions, such as catheter placements or joint injections. During a fluoroscopy exam, a patient may be asked to swallow a contrast material, which helps highlight specific areas. The images are displayed on a monitor, enabling healthcare professionals to assess conditions and make informed decisions about treatment.
