Data are presented as mean ± SD. Friedman test was conducted to obtain the p values to compare the data obtained using 4, 6, 8, 10, and 12 projections (post-hoc pairwise comparisons). ICA, internal carotid artery; ACA, anterior cerebral artery; MCA, middle cerebral artery.

Adjusted p < 0.05, comparison between scores of 4 and 8 projections by post-hoc pairwise comparisons.

Adjusted p < 0.05, comparison between scores of 4 and 10 projections by post-hoc pairwise comparisons.

Adjusted p < 0.05, comparison between scores of 4 and 12 projections by post-hoc pairwise comparisons.

Adjusted p < 0.05, comparison between scores of 6 and 8 projections by post-hoc pairwise comparisons.

Adjusted p < 0.05, comparison between scores of 6 and 10 projections by post-hoc pairwise comparisons.

Adjusted p < 0.05, comparison between scores of 6 and 12 projections by post-hoc pairwise comparisons.

Adjusted p < 0.05, comparison between scores of 8 and 12 projections by post-hoc pairwise comparisons.

Adjusted p < 0.05, comparison between scores of 4 and 6 projections by post-hoc pairwise comparisons.
