Synopsis

Keywords: Breast, Breast

Motivation: Diagnosis of lesions shown as architectural distortion (AD) on DBT is challenging, and breast MRI may help.

Goal(s): To compare the diagnostic performance of 60 cases using reading based on BI-RADS of DBT and MRI, Kaiser score, and radiomics models.

Approach: In addition to comparing the diagnostic performance, features shown on DBT and MRI, and the distribution in different MRI BI-RADS categories, were reported.

Results: The malignant rate of AD varied in associated features and MRI-RADS groups. MRI showed better diagnostic performance than DBT. When using radiomics models, the accuracy was almost the same, but the AUC of DBT+MRI fused model improved.

Impact: Diagnosis of lesions presenting as AD on DBT can be improved with more understanding of associated features, as well as the predictive features based on the supplementary MRI.
