To evaluate the rate of unnecessary follow-up procedures recommended by radiologists using a CAD-system.
Materials and methods
185 patients (740 images) were consecutively selected from three groups (36 histologically proven cancers=group 1; 49 histologically proven benign lesions=group 2 and 100 screening cases (4 years-follow up=group 3). Mammograms were evaluated by a CAD system (Second Look®, CADx, Canada). Five blinded radiologists assessed the images without/with CAD outputs. Diagnostic decisions were ranked from surely benign to surely malignant according to BIRADS classification, follow-up procedures were recommended for each observed lesion (a, screening; b, short interval follow-up examination in 6 months; c, pathologic clarification).
Results
CAD-system detected 32/36 cancers (88.9%) (FP-rate: 1.04 massmarks and 0.27 calcmarks/image). The following values …
