What Is the Difference Between Fluoroscopy and Radiography?

Reviewed on 1/29/2021

What are fluoroscopy and X-ray?

Radiography or X-ray and fluoroscopy procedures seem similar. However, fluoroscopy obtains moving images of the inner part of the body and radiography uses gamma rays to develop a static image of the internal structure of a body.

Radiography or X-ray and fluoroscopy procedures seem similar. However, fluoroscopy obtains moving images of the inner part of the body and radiography uses gamma rays to develop a static image of the internal structure of a body. We can compare X-ray to a black and white photograph and fluoroscopy to a black and white animation.

How are X-ray and fluoroscopy different?

The technique used for X-ray and fluoroscopy technology is essentially the same with a few notable differences. They both use radiation energy on a particular part of the bone or body cavity for the purpose of obtaining images. Their other functions are

  • X-rays are static images. They provide still images of the inside of the body.
  • Fluoroscopy imaging provides a live “video” format image, which will show movements inside the body or of an instrument in the body.
  • Fluoroscopy when done with contrast can highlight the inner lining of tubular organs of the body. These studies can help us study the ulcerations, localized narrowing of a particular part, etc.
  • Theoretically, X-rays carry a smaller risk of radiation-related risks than fluoroscopy. Since fluoroscopy requires serial X-rays, the exposure time is greater.

What are the common types of fluoroscopy?

Fluoroscopy is an innovative technology that offers many benefits using X-rays. It uses the same technology as an X-ray to generate a working image for a doctor to interpret and decide a course of treatment for the patient. It creates the images in a video form, which can open many other opportunities for its usefulness. The fluoroscope allows the doctor to visualize the interior of the body as it moves and functions. Below are common types of fluoroscopy
