Pre-operative visualization of cerebral vasculature using photon-counting CT ultra-high resolution pure lumen imaging

Introduction

Preoperative neuronavigation relies on multimodal imaging to delineate lesion anatomy and surrounding neurovascular structures. Ultra-high-resolution photon-counting CT (UHR PCCT) provides submillimeter vascular and osseous detail and may improve surgical planning compared with conventional CT and MRI. Research question: To evaluate the potential added value of UHR PCCT for preoperative neuronavigation in selected complex intracranial lesions.
