Motivation: Previous studies have not developed a high-resolution wall imaging scoring system for TA patients with intracranial vascular involvement to explore its relationship with intracranial lesions.
Goal(s): Develop a HR-VWI score to demonstrate the relationship between the score and incidence of intracranial lesions.
Approach: Integrated the degree of luminal stenosis, the pattern and degree of vessel wall enhancement and the number of affected vessels on HR-VWI into a HR-VWI score.
Results: TA patients with intracranial lesions had higher HR-VWI scores and HR-VWI scores performed well in distinguishing TA patients with intracranial lesions from those without intracranial lesions.
Impact: HR-VWI is a powerful tool for physicians to visualize the condition of vessels by showing the various changes in the vesseel walls and a more reliable method of diagnosing intracranial arterial stenosis than TOF-MRA.
