We compared the detection of clustered microcalcifications by means of conventional mammograms and by means of secondary digitized images with a spatial resolution of 2048 x 1684 pixels and a contrast resolution of 12 bit. A Receiver Operating Characteristic (ROC) study was carried out using a cadaver breast showing phantom microcalcifications. A set of 100 mammograms was evaluated by two experienced senior radiologists. The ROC scores obtained with the digital images were 10% lower than those obtained with the conventional images. This difference however does not reach statistical significance. The use of a digital zoom function based on pixel duplication is also investigated. This zoom function does not produce a change in the diagnostic accuracy of the digital method. Attention is also paid to the advantages and disadvantages encountered by the radiologists when working on the digital viewing system. The most important drawback seems to be that it is considerably more time consuming than the conventional procedure, and this is especially due to the long loading time of the images and to the absence of window and level preselections.
