Comparison of core tissue amount measured by the AMUS concerning the histological diagnosis as determined by the ROC analysis. (a) In the isolation group, ROC curves based on the amount of whitish core measured by the AMUS concerning the histological diagnosis are shown. The AUC was 0.80 (95% CI: 0.62–0.97, p < 0.01). (b) In the no‐isolation group, ROC curves based on the amount of whitish core measured by the AMUS concerning the histological diagnosis are shown. The AUC was 0.84 (95% CI: 0.72–0.96, p < 0.01). (C) ROC curves based on the amount of whitish core measured by the AMUS concerning the histological diagnosis are shown. The AUC was 0.84 (95% CI: 0.71–0.92, p < 0.01). AMUS, automated multiband imaging system; AUC, area under the curve; CI, confidence interval; ROC, receiver‐operating characteristic
