Abstract:
Objective To explore the application value of adaptive window width and level algorithm in 3D vascular reconstruction from head and neck CT angiography for achieving consistent reconstruction results at different contrast agent dosages.Methods Both direct vascular reconstruction and reconstruction after applying adaptive window width and level algorithm were conducted in 100 cases undergoing head and neck CT angiography;and the reconstruction results were compared.Results In the cases with excessive or insufficient contrast agent,the overall effect of reconstructions using adaptive window width and level algorithm was superior to that of direct reconstruction,particularly in displaying intracranial small vessels and plaques.Conclusion The adaptive window width and level algorithm has high application potential in vascular reconstruction from head and neck CT angiography,and demonstrates superior generalization in highlighting plaques,adapting to different contrast agent dosages,and displaying intracranial small vessels.
