Description

We constructed a database of mammograms obtained with five commercial full-field digital mammography (FFDM) systems at four institutions. The aim of this research was to compare the thickness of the compressed breasts between the mediolateral oblique (MLO)- and craniocaudal (CC)-view images of 2,772 mammograms obtained from 807 patients in the database. The average compressed breast thickness in the MLO-view images was less than that in the CC-view images (42.50 mm vs. 44.11 mm, p<0.001) despite the greater force used to compress the breast for obtaining the MLO-view images than for obtaining the CC-view images (92.44 vs.89.38 newtons, p<0.01).
