  • Note:—The numbers in the table represent the number of times that each combination of scores was given by participating neuroradiologists.
  • * Modified scores: 0, quite certainly the wrong diagnosis; 1, probably the wrong diagnosis; 2, equivocal; 3, probably the right diagnosis; and 4, quite certainly the right diagnosis.
