Automatic EEG spike detection: what should the computer imitate?

摘要: We conducted a study to explore how electroencephalographers (EEGers) read EEGs and reach clinical impressions based upon them. Eight EEGers rule-based computerized "spike" detector marked epileptiform discharges ("EDs") in 12 test records. Of all events, 18% were by readers 38% only one reader. Readers agreed on basic features of the records, such as whether record demonstrated EDs, rank order ED sources location, ranking records number EDs detected. consistent pattern that was independent an objective measure expertise experience. Our had lower sensitivity selectivity than human readers, but either parameter could be adjusted comparable at expense other. propose employ reproducible, quantitatively different styles reading EEG tracings qualitatively similar impressions. In practice, are not absolutely defined, appear represent continuum activity which lends itself better description ordering absolute quantitation.
