Assessment of image quality and feasibility of Photon-Counting detector CT for the Non-Contemporaneous follow-up of intracranial aneurysms treated with flow diverter stents.

PCD-CT provides superior stent lumen visualization compared to baseline imaging, while maintaining a sub-millisievert radiation dose, and represents a promising non-invasive surveillance tool, though prospective validation of its diagnostic accuracy for in-stent stenosis is required.
