Abstract

The object of this study was to assess the clinical usefulness of computer-assisted diagnosis (CAD) in the interpretation of early-research, benign and malignant mammograms in dependence on readers' experience with CAD. CAD was applied on digital mammograms of 303 patients who were divided into three groups: early-research (n=103), benign (n=102) and malignant group (n=98). Mammograms were analyzed by three readers with different experience in evaluating mammograms (medical student, an assistant and an attending physician specifically trained in mammography). All images were presented accidentally with and without the influence of CAD and from different patient groups. The mammograms were classified according to BI-RADS classification. To evaluate readers' sensitivity and specificity with and without the application of the CAD system, ROC analysis and the corresponding area under the curve (AUC) were evaluated for each reader. Afterwards significant differences of the accuracy according to readers experience and according to the assistance of the CAD system were calculated. All readers have an account of accuracy by using CAD in both patient groups. The highest benefit has the student (10% increase of the AUC) followed by the r...Continue Reading
