Breast Sonographic Elastography Using an Advanced Breast Tissue-Specific Imaging Preset Initial Clinical Results

Results—The values for the area under the receiver operating characteristic curve were 0.959 (95% confidence interval [CI], 0.902–0.987) for conventional sonography and 0.901 (95% CI, 0.829–0.949), 0.796 (95% CI, 0.708–0.866), and 0.787 (95% CI, 0.699–0.859) for the strain ratio, size ratio, and elasticity score, respectively. When a strain ratio cutoff point of 4.215 was used, the sensitivity and specificity were 86.0% and 85.1%. With a best cutoff point for conventional sonography between Breast Imaging Reporting and Data System categories 4A and 4B, the sensitivity and specificity were 93.0% and 83.6%. Conclusions—The strain ratio showed the best diagnostic performance among the interpretation criteria for sonographic elastography with the tissue-specific imaging preset. The diagnostic performance was slightly higher for Breast Imaging Reporting and Data System categories than for the strain ratio. However, there was no statistical significance (P = .052).
