Abstract :
Our goal is to know how the differences detected in the quality control program become apparent in clinical mammograms. The results of the quality control were correlated with the clinical detectability through true-positive and true-negative determination. The quality control program is able to show variations also detected as clinical features when different screen/film systems are used
