Which imaging modality is commonly used for real-time imaging during procedures?

• A. Mammography
• B. Fluoroscopy
• C. CT
• D. MRI

Answer: (B)

Real-time imaging during procedures relies on a modality that can continuously display moving images as instruments are advanced. Fluoroscopy provides just that: it produces a live X-ray video so clinicians can watch the tip of a catheter, needle, or device move in real time and see how contrast flows through vessels or spaces. This immediate feedback is essential for guiding interventions safely and accurately. Mammography is designed for static breast imaging and isn’t used to guide procedures in real time. CT delivers fast, cross-sectional images, but those are discrete snapshots rather than continuous video, making real-time guidance impractical. MRI can show dynamic images, but interventional MRI is less common due to setup, cost, and workflow constraints. For the standard need of live guidance during procedures, fluoroscopy is the go-to choice.
