title: Clinical Utility of Angiographic CT with a Flat-detector Angiographic System during Endovascular Procedure.
abstract: OBJECTIVE
  We evaluated the feasibility of angiographic computed tomography (ACT) for visualizing stent material in patients who underwent intracranial or extracranial stent placement to treat atherosclerotic lesions or stent assisted coil embolization.
  
  
  METHODS
  We performed intrarterial and intravenous ACT on biplane angiography system equipped with flat panel detectors (Axiom Arits dBA; Siemens Medical Solutions, Forchheim, Germany). Vistipaque 320 was injected for contrast medium, total 150 mL at flow rate of 5 mL/s through artery and 77 mL at flow rate of 3.5 mL/s through vein.
  
  
  RESULTS
  ACT is a new imaging modality that provides a clear visualization of stent strut.
  
  
  CONCLUSIONS
  Therefore this new application has potential to become the noninvasive option for follow-up after endovascular surgery using stents.
