CAD provides human readers withlocation (and characterization) of potential lesions

final diagnostic decision is made by the reader

Computer-Aided Diagnosis

Look here !!!

Improve diagnostic performanceincrease sensitivity and specificity

decrease inter- and intra-reader variability

Improve productivityread more cases without significantly increasing interpretation time

Improve patient managementprovide patients with exams options

provide physicians with decision support
