What is the role of real-time imaging in fluoroscopy?

The role of real-time imaging in fluoroscopy is primarily to observe dynamic functions during procedures. This capability allows healthcare professionals to see physiological processes as they happen, providing crucial insights into the function of organs or systems in real-time. For instance, during gastrointestinal studies, fluoroscopy can show the movement of contrast material through the digestive tract, which helps assess motility and identify abnormalities.

While still images can be taken during fluoroscopic procedures for documentation, that is not the primary purpose of real-time imaging. Analyzing previous results doesn't align with the function of fluoroscopy, as it focuses on the immediate visualization of ongoing processes. Additionally, preparing patients for anesthesia pertains to pre-procedural planning rather than the role of imaging during the actual fluoroscopy. Thus, the correct answer highlights the essential function of fluoroscopy in providing dynamic visualization that assists clinicians in making informed decisions during procedures.
