Confusion matrices for the artificial intelligence system and radiologists. Confusion matrices for different radiologist specialization levels were generated for the top diagnosis, averaged across individuals within each group. True disease labels are shown along the x-axis and predicted diagnoses on the y-axis. The color of each cell represents the fraction of cases within a column where the top predicted diagnosis matched the true diagnosis. Artery of Perch = artery of Percheron, Bilat thal glioma = bilateral thalamic glioma, Carbon Mon Acute = carbon monoxide: acute, Carbon Mon Chronic = carbon monoxide: chronic, Carbon Mon Subacute = carbon monoxide: subacute, CNS = central nervous system, Creutzfeld Jacob = Creutzfeldt-Jakob disease, DVT = deep vein thrombosis, Hemorrhage Chron = hemorrhage: chronic, Hemorrhage Subac = hemorrhage: subacute, High GR = high grade, HIE = hypoxic-ischemic encephalopathy, Infarct Chron = infarct: chronic, Low GR = low grade, Neuro Behcets = neuro Behçet disease, Neurofibromat 1 = neurofibroma type 1, Neurorad fellows = neuroradiology fellows, Neurosarcoid = neurosarcoidosis, Nonketot hypergly = nonketotic hyperglycemia, Wernickes = Wernicke encephalopathy, Wilsons = Wilson disease.
