Radiology-guided interventions commonly rely on which imaging modalities to guide procedures?

• A. Fluoroscopy, CT, or ultrasound
• B. Only fluoroscopy
• C. Only CT
• D. Only ultrasound

Answer: (A)

Radiology-guided interventions rely on real-time imaging to steer needles, catheters, or probes to the target while watching for safety. Fluoroscopy provides continuous X-ray video and contrast flow, which is especially helpful for guiding devices through soft tissue and into vessels or ducts, making it a staple for many vascular and endovascular procedures. CT gives high-resolution cross-sectional detail and precise 3D localization, so it’s excellent for planning and confirming needle placement in deep or anatomically complex areas such as the liver, lung, spine, or other solid organs. Ultrasound offers real-time visualization without ionizing radiation and is particularly useful for superficial targets or when a safe, bedside approach is preferred, such as guiding a biopsy or needle drainage near vessels and organs. Often, clinicians combine these modalities to leverage their strengths—ultrasound for initial access, fluoroscopy for device advancement and dynamic guidance, and CT for final confirmation of position. That blend is why radiology-guided interventions commonly rely on fluoroscopy, CT, or ultrasound.
