Abstract：Objective To explore the application of fused images,acquired through high-resolution cone-beam computed tomography(CBCT)and 3-dimensional digital subtraction angiography(3D-DSA),in assessing the apposition of flow diverters(FD).Methods Fifteen patients who underwent flow diverter placement in were subjected.Following the deployment of the flow diverter,high-resolution CBCT and standard 3D-DSA scans were conducted.Image fusion was then executed on a post-processing workstation,allowing for the comprehensive assessment of the FD's adherence to the vessel wall from any perspective within the three-dimensional fusion image.Results Fusion images combining high-resolution CBCT and 3D DSA were successfully generated for all patients.These images facilitated the evaluation of FD wall adherence from any angle,revealing that 13 cases exhibited good adherence while 2 cases showed poor adherence.Conclusions Three-dimensional fusion images provide a clear and intuitive visualization of the relationship between the flow diverter and the parent artery,enabling multi-angle assessments and thereby enhancing the precision of the evaluation process.
