N2 - The study presents an application of the case-specific reliability analysis framework for quality evaluation of mammographic CAD detections. First, the original framework is modified so that it can be applied to a featureless case-based CAD system that relies on principles of information theory (IT). Then, the IT-CAD system is applied for false positive reduction of visual cues provided by a pre-screening algorithm. The study is based on mammograms from the Digital Database of Screening Mammography (DDSM) and is focused on mass detection. Experimental results show that assessment of the expected accuracy for each individual CAD cue facilitates 11%-18% further reduction of false positives while operating at high mass detection rates.
