Which statement correctly describes preparation for a DSA run-off procedure?

• A. Patient is supine, legs secured, table at the highest height, flat plate set to the lowest level, and image magnification set to the lowest level
• B. Patient is prone, legs unsecured, table at the lowest height, magnification set to high
• C. Patient is seated, legs elevated
• D. Patient is supine, legs secured, table at mid-height, magnification set to medium level

Answer: (A)

For a DSA run-off, you want a setup that gives you stable patient positioning while maximizing the field of view to see the entire arterial run (from the aorta through the legs) and keeps the access site easily reachable. A supine position is standard for arterial access and consistent anatomy, and securing the legs prevents movement during multiple acquisitions and catheter manipulation. Placing the table at the highest height improves ergonomic access to the femoral puncture site and aligns the patient for straightforward imaging of the lower vascular tree. Keeping the image receptor level low helps maintain a broad field of view with minimal geometric distortion, and using the lowest magnification preserves that wide view while reducing radiation exposure. In short, this setup optimizes visibility of the full runoff and keeps catheter navigation practical and stable.
