Angiography of the celiac artery using caudal or cephalic beam angulation

Celiac arteriography in the frontal projection with the tube angled 50° toward the feet demonstrated an aneurysm which arose from the celiac artery and did not involve the splenic or hepatic artery. Angling the tube toward the feet (or toward the head if the celiac artery ascends) is recommended for evaluation of the celiac, proximal splenic, and hepatic arteries.
