4.4 Initial calibration for computer-aided detection technologies

When CAD is implemented, local calibration is advised to customize the score thresholds to the requirements of the programme (see the operational handbook for more details about how this can be done) (7). After this initial calibration, ongoing monitoring and analysis of CAD performance should be carried out to assess the correlation with human readers’ interpretations and with bacteriological confirmation, and with the proportion of images read as abnormal and requiring further investigation.
