Question: 1 / 400

Which imaging modality is recognized for its ability to evaluate real-time motion?

CT Scan

X-ray

Ultrasound

Fluoroscopy

Fluoroscopy is recognized for its ability to evaluate real-time motion due to its continuous X-ray imaging capabilities. This technique allows healthcare providers to observe dynamic processes within the body, such as the movement of organs, passage of contrast agents through the gastrointestinal tract, or the function of the musculoskeletal system during various activities. The real-time imaging produced by fluoroscopy is critical for procedures that require live feedback, such as guiding catheter placements or assessing swallowing function.

While other imaging modalities like ultrasound can also provide some real-time imaging, fluoroscopy stands out because of its continuous, nearly instant visualization of anatomical structures and functions as they occur. This makes it particularly valuable in interventional radiology and various diagnostic examinations that require an assessment of motion.
