Summary

This prospective observational study aims to evaluate the effectiveness of ultra-high-resolution photon-counting CT angiography (UHR PCD-CTA) for noninvasive assessment of intracranial venous sinus stents. The study will compare image quality, stent visualization, metal-related artifacts, and diagnostic accuracy between PCD-CTA and conventional energy-integrating detector CT angiography (EID-CTA).
