Abstract
Computer-aided diagnosis (CAD) is a diagnosis made by a physician who takes into account the results of quantitative analysis of medical images by computer. The CAD systems, especially called as computer-aided detection (CAD) systems, are now commercially available at least in the two diagnostic fields, i.e., breast cancer diagnosis by mammograms (automated detections of masses and clustered microcalcifications) and thoracic cancer diagnosis by chest radiograms and X-ray CT images (automated nodule detection). Recent studies have indicated promising results in that the computer output can improve the performance of radiologists in detecting lesions on radiographic images. The CAD will make rapid progress to different modalities and various diagnostic regions. In this article, the latest information on mammography CAD for breast image diagnosis is mainly provided with a brief description on ultrasound CAD.
