What is the primary advantage of fluoroscopy in interventional procedures?

• A. Real-time dynamic visualization to guide instrument placement
• B. High-resolution static 3D imaging
• C. Preoperative planning only
• D. No radiation exposure

Answer: (A)

Real-time dynamic visualization to guide instrument placement during interventions. This live imaging lets you watch the exact position and movement of catheters, wires, and devices as you navigate the vasculature or other anatomy, so you can adjust in the moment, verify successful catheter position, and monitor the effect of your intervention. It provides immediate feedback that static images cannot, which is essential for precision and safety during procedures. In contrast, high-resolution static 3D imaging like CT or MRI offers detailed anatomy but not continuous live guidance and is typically used for planning or diagnostic assessment rather than intra-procedural navigation. Preoperative planning is a separate use case, and fluoroscopy does involve radiation exposure, so statements about no radiation aren’t correct.
