[Spiral tomodensitometry applied to interventional radiology]

Abstract

Spiral CT can be applied to many interventional procedures. Rapid scanning time reduces the duration of percutaneous CT guided biopsy and examination time of polytrauma patients. 3D reconstructions are applied to the planning and follow-up of vascular interventional procedures such as embolization of aneurysms or arteriovenous fistulae, stent grafting of aortic aneurysms or dissection, percutaneous transluminal angioplasty of the renal arteries, supra-aortic or iliac arteries. TIPS, percutaneous biliary procedures and percutaneous treatment of liver tumors do largely benefit from 3D reconstructions as a planning method.
