True positive (TP), false positive (FP), true negative (TN), and false negative (FN) rates, as well as sensitivity and specificity for identifying each artery with AAIM are also presented. Without any TN or FP, it is not possible to calculate specificity

ICA Internal carotid artery, VA Vertebral artery, BA Basilar artery, PCA Posterior cerebral artery, MCA Middle cerebral artery, ACA Anterior cerebral artery, PCoA Posterior communicating artery
