As compared to the separate evaluation of the standard MRI and diffusion images, the addition of image fusion did not improve the performance of the readers in our study.
More importantly, the poor absolute agreement in detecting change should be judged against the background of an extremely low previous probability of change, which may influence the performance of the readers.
> The performance of the average reader increased with CAD at low false-positive rates from 25.1%to34.8%8%.
Performance of the plate reader was qualified each month using a Dynex calibration plate certified by the UK National Physics Laboratory (NPL, Rugby, England).
We stress the fact that, assuming that an optimal power control policy exists, the performance of the multi-reader system strictly depends on the performance of a single-reader system in terms of tag speed identification and query success rate.
On the contrary, if we fixed the value of M according to the reader that covers the maximum number of tags, as expressed in (19), we assure to have the same performance of the single-reader scenario at the cost of increasing the number of time slots required for tag identification.
A difference in performance of the two readers was observed.
Furthermore, it should be noted that this variability in the performance of the two readers may have led to an over- or under-estimation of the sensitivity improvement achieved using LED FM.
All the nonimpaired readers had a reading quotient above 95, corresponding to percentile 37. Thus, reading performance of the best dyslexic reader and the worst nonimpaired reader differed in more than 1 SD.
