Utility of Non-Contrast CT and MRA Fusion Images for Depicting Occluded Vessels in Mechanical Thrombectomy

Objective: Mechanical thrombectomy (MT) for acute ischemic stroke usually requires blind procedures when endovascular devices are advanced distal to the occlusion site. Visualization of vascular structures distal to the occlusion could potentially enable safer procedures and more effective recanalization. We report the usefulness of fusion images using non-contrast CT and MRA with Ziostation REVORAS (Ziosoft, Tokyo, Japan).
