Abstract

Objectives

To compare three-dimensional high-resolution magnetic resonance imaging (3D HR-MRI) and digital subtraction angiography (DSA) for diagnosing and evaluating stenosis in the entire circle of Willis.

Methods

The study included 516 intracranial arteries from 43 patients with intracranial artery stenosis (ICAS) who underwent both 3D HR-MRI and DSA within 1 month. Two readers independently diagnosed atherosclerosis, dissection, moyamoya disease and vasculitis, rated their diagnostic confidence for each vessel and measured the luminal diameters. Reference standard was made from clinico-radiologic diagnosis. Diagnostic accuracy, diagnostic confidence, the degree of stenosis and luminal diameter were assessed and compared between both modalities.

Results

For atherosclerosis, 3D HR-MRI showed better diagnostic accuracy (P = .03–.003), sensitivity (P = .006–.01) and positive predictive value (P ≤ .001–.006) compared to DSA. Overall, the readers were more confident of their diagnosis of ICAS when using 3D HR-MRI (reader 1, P ≤ .001–.007; reader 2, P ≤ .001–.015). 3D HR-MRI showed similar degree of stenosis (P > .05) and higher luminal diameter (P < .05) compared to DSA.

Conclusions

3D HR-MRI might be useful to evaluate atherosclerosis, with better diagnostic confidence and comparable stenosis measurement compared to DSA in the entire circle of Willis.

Key Points

3D HR-MRI showed better diagnostic accuracy for atherosclerosiscompared to DSA
3D HR-MRI showed better overall diagnostic confidence for stenosiscompared to DSA
3D HR-MRI and DSA showed similar degree of stenosis
