What positioning technique is described for Carotid or Vertebral Angiography?

• A. Head on head sponge with chin tucked to chest
• B. Supine with neck extended
• C. Prone with neck rotated
• D. Lateral decubitus with head turned

Answer: (A)

Positioning for carotid or vertebral angiography aims to place the neck vessels in a clear, single plane so the arteries can be imaged without obstruction. The described setup—head resting on a sponge with the chin tucked toward the chest—slightly flexes the neck, bringing the common carotid artery and its bifurcation into a more anterior, the-necks-and-vessels-in-line projection. This reduces overlap from the mandible and shoulder structures, improves beam alignment with the vessel path, and helps keep the head stable during catheter manipulation. The sponge provides support to maintain a reproducible position and comfort. Other positions tend to increase overlap or misalign the vessels, making the angiographic view less optimal.
