The number of patients for each score (5/4/3/2/1) is shown
ACA anterior cerebral artery; BG basal ganglia; DLR deep learning reconstruction; Hybrid IR hybrid iterative; N/A not applicable; PCA posterior circulation; sub-MCA middle cerebral artery at level basal ganglia: and sup-MCA middle cerebral artery at the level of the ventricles above the basal ganglia
Comparisons were performed with the Wilcoxon signed-rank test
