Objective ToexploretheapplicationofVasoCT,astentimagingtechnique,instent-assisted coilaneurysmembolization.Methods Twentyconsecutivepatientswith23intracranialaneurysmswere treated with stent-assisted aneurysm embolization in the General Hospital of Armed Police Forces from December 2013 to November 2014 were enrolled. The patients performed VasoCT scan immediately after procedure. Then all the available images were used for stent-optimized reconstruction respectively. Under the XpertCT mode,the available images were observed with both volume imaging and maximum intensity projection. The available images were analyzed and they were divided into very clear,less clear,and not clearaccordingtothestentdevelopingclarity.Results Ofthe22aneurysmstreatedwithstent-assisted embolization,16 were occluded completely,6 were occluded partially. All the stents were expanded completely and were released to the expected locations;11 aneurysm stents developed clearly,9 developed less clearly,and 2didnotdevelopclearly.Conclusion VasoCTcanbeusedinthestent-assistedaneurysmembolization.It can clearly reveal the microscopic structure of the stents,location,relationship with the artery wall,and relationship between stents and coils. The clarity of stent development is associated with the diameters of the packed coils,and the stents are also affected by the metal artifacts projecting direction and the dense degree of the packing coils.
