Interpretation of patterns of enhancement on contrast-enhanced spectral mammography: An approach to a standardized scheme

This study included 104 malignant lesions versus 74 benign. Diagnostic accuracy parameters for CESM were sensitivity 98% (102/104) and specificity 76% (56/74). Irregular margin intense enhancement focus (1/8) was diagnosed malignant, (7/8) while regular margin faint enhancing foci were benign.Irregular shape, spiculated margin and heterogeneous internal enhancement descriptors of mass lesion descriptors conformed to malignancy (PPV 92.5% of the former and 88.7% of the latter, p value ≤ 0.001).Asymmetry with segmental distribution, (17/27) (70.8%) heterogeneous and clumped internal enhancement patterns were indicative for malignancy in non mass enhancement (PPV

ConclusionOur results demonstrate performance inconsistency across the data sets and models, indicating that the high performance of deep learning models on one data set cannot be readily transferred to unseen external data sets, and these models need further assessment and validation before being applied in clinical practice.

Performance of recently developed deep learning models for image classification surpasses that of radiologists. However, there are questions about model performance consistency and generalization in unseen external data. The purpose of this study is to determine if the high performance of deep learning on mammograms can be transferred to external data with a different data distribution.

This study aimed to evaluate the added value of digital breast tomosynthesis (DBT) to BI-RADS classification in categorization of indeterminate breast lesions after digital mammography (DM) as an initial approach.Methods and resultsWe prospectively evaluated 296 women with BI-RADS indeterminate breast lesions (BI-RADS 0, 3, and 4) by DM between January 2018 and October 2019. All patients underwent DBT. Two radiologists evaluated lesions and assigned a BI-RADS category to each lesion according to BI-RADS lexicon 2013 classification using DM, DBT, and combined DM and DBT. The results were compared in terms of main radiologic...
