Although the subjective conspicuity of microcalcifications was found to be significantly better on digital mammography compared to film-screen mammography, there was no significant advantage of digital mammography resulting from the higher contrast resolution nor a disadvantage in terms of characterization of microcalcifications resulting from the lower spacial resolution. The advantages of digital mammography (e. g. CAD-systems, archiving, dose reduction) can be used without a loss of diagnostic quality.
