What key feature differentiates fluoroscopy from conventional radiography?

The distinguishing feature of fluoroscopy is its ability to provide real-time visualization of moving internal structures. This dynamic imaging encompasses a continuous series of images that allow healthcare professionals to observe motion, such as the functioning of organs or the progression of a contrast agent through the body. This is particularly useful in diagnostic procedures, guiding interventions, or assessing conditions on-the-fly.

In contrast, conventional radiography typically involves capturing static images on film or digital sensors, which do not capture movement or dynamic processes. While fluoroscopy does use radiation, it is a continuous source of exposure, rather than a singular snapshot, which is characteristic of conventional radiographic techniques. Additionally, fluoroscopy is applicable in a variety of settings, not solely limited to therapeutic procedures. Its primary advantage lies in the visualization of real-time movement, making it an essential tool in medical imaging.
