Objective: To compare new full-field digital. mammography (FFDM) with and without use of an advanced post-processing algorithm to improve image quality, lesion detection, diagnostic performance, and priority rank. %26lt;br%26gt;Materials and Methods: During a 22-month period, we prospectively enrolled 100 cases of specimen FFDM mammography (Brestige (R)), which was performed alone or in combination with a post-processing algorithm developed by the manufacturer: group A (SMA), specimen mammography without application of %26quot;Mammogram enhancement ver. 2.0%26quot;; group B (SMB), specimen mammography with application of %26quot;Mammogram enhancement ver. 2.0%26quot;. Two sets of specimen mammographies were randomly reviewed by five experienced radiologists. Image quality, Lesion detection, diagnostic performance, and priority rank with regard to image preference were evaluated. %26lt;br%26gt;Results: Three aspects of image quality (overall quality, contrast, and noise) of the SMB were significantly superior to those of SMA (p %26lt; 0.05). SMB was significantly superior to SMA for visualizing calcifications (p %26lt; 0.05). Diagnostic performance, as evaluated by cancer score, was similar between SMA and SMB. SMB was preferred to SMA by four of the five reviewers. %26lt;br%26gt;Conclusion: The post-processing algorithm may improve image quality with better image preference in FFDM than without use of the software.
