| Research Abstract |
The purpose of this study was to develop a computer-aided diagnosis system that searches for similar already-diagnosed images as a reference. First, we have established a new digital mammography database and determined image features by computerized analysis. The gold standard of similarity for selecting reference images was obtained by experts. Using an artificial neural network and multidimensional scaling, we were able to determine similarity measures that correlate well with the gold standard. In the observer study, diagnostic accuracies were slightly improved by the presentation of similar images for both physician and radiological technologist groups.
