Fluoroscopy is a continuous X-ray procedure that shows the heart and lungs and is still used as part of cardiac catheterization.

• A. Fluoroscopy
• B. Echocardiography
• C. CT scan
• D. Bronchoscopy

Answer: (A)

Real-time imaging with X-rays to guide invasive procedures is what this question is about. Fluoroscopy provides continuous X-ray video, so clinicians can watch the heart, vessels, and any inserted catheters move in real time as contrast flows. That real-time guidance is essential during cardiac catheterization, allowing precise placement and assessment as the procedure progresses.

Echocardiography uses ultrasound to image heart structures and function, not X-ray radiography, so it doesn’t provide the same continuous radiographic guidance. CT scans offer detailed static cross-sectional images rather than live video during a procedure. Bronchoscopy visualizes the airways with a scope, not the heart and vessels via X-ray imaging.
