Comparison of two-dimensional synthesized mammogram (2DSM) and conventional full-field digital mammogram (FFDM) for evaluation of breast cancer

Abstract

Purpose: To compare the diagnostic efficacy of 2DSM and FFDM for evaluation of breast cancer. Materials and methods: A retrospective observer performance study was done by 3 breast radiologists. The diagnostic accuracy, image quality, and detailed lesion characterization of each 2DSM and FFDM were evaluated blindly to determine superior modality. Results: The diagnostic accuracy was not significantly different between two modalities. The image quality was superior in 2DSM (p-value 0.0362). Conclusions: 2DSM showed equivalent diagnostic accuracy and superior image quality to FFDM. Overall characterization of the lesion was better in 2DSM, and 2DSM showed superiority in evaluation of spiculated margins. (C) 2017 Elsevier Inc. All rights reserved.
