Cross-sectional imaging modalities have become indispensable in modern medical diagnostics, offering detailed anatomical visualization with minimal invasiveness[1,2]. Computed tomography (CT), in particular, has significantly advanced neurovascular imaging, facilitating the assessment of intracranial and cervical arteries with high spatial resolution and rapid acquisition times. CT cerebral angiography (CTCA) is extensively utilized to evaluate vascular abnormalities such as aneurysms, arteriove…
