Dyna three-dimensional imaging enables reliable evaluation of neointimal formation after flow diverter treatment.

ABSTRACT: BackgroundFlow diverter stent (FDS) treatment is an effective option for wide-necked intracranial aneurysms, but adequate neointimal formation and stent apposition are critical to prevent thromboembolic complications. Non-invasive, reliable imaging techniques for assessing neointimal formation remain limited. This study aimed to evaluate the utility of Dyna-3D imaging in assessing neointimal formation after FDS treatment and to compare its performance with conventional 2D-DSA.MethodsThis retrospective study included 61 patients with unruptured intracranial aneurysms treated with FDS between August 2019 and October 2024. Radiological follow-up was performed 3-6 months post-procedure using both 2D-DSA and Dyna-3D imaging. Neointimal coverage was classified into Groups A-C based on the positi
