How is fluoroscopy different from standard X-ray imaging?

Fluoroscopy is distinct from standard X-ray imaging primarily because it provides real-time moving images instead of capturing only still images. This capability allows physicians to observe dynamic processes within the body, such as the movement of organs, the flow of contrast agents, or the function of the gastrointestinal tract. By using a continuous X-ray beam, fluoroscopy can display a sequence of images that enable the clinician to assess motion and function, which is essential for certain diagnostic and therapeutic procedures.

In contrast, standard X-ray imaging generally involves taking a single snapshot at a moment in time, which can provide detailed information about the structure of tissues and organs but cannot convey changes or movement. Other mentioned options refer to concepts not applicable to fluoroscopy, like the absence of radiation or reliance on magnetic fields, which do not accurately describe the characteristics of this imaging technique.
