Highlights |
• | A deep learning-based software is able to detect and quantify breast arterial calcifications on mammogram with a strong correlation with manual scoring in an external validation cohort. |
• | A high level of breast arterial calcifications as detected by the deep learning-based software, is associated with a high coronary artery calcium score and therefore a higher risk of death from cardiovascular disease. |
• | Automated quantification of breast arterial calcifications could be a useful tool to improve awareness of a woman's cardiovascular risk status. |
Abstract |
Purpose |
The purpose of this study was to evaluate an artificial intelligence (AI) software that automatically detects and quantifies breast arterial calcifications (BAC).
Materials and methods |
Women who underwent both mammography and thoracic computed tomography (CT) from 2009 to 2018 were retrospectively included in this single-center study. Deep learning-based software was used to automatically detect and quantify BAC with a BAC AI score ranging from 0 to 10-points. Results were compared using Spearman correlation test with a previously described BAC manual score based on radiologists’ visual quantification of BAC on the mammogram. Coronary artery calcification (CAC) score was manually scored using a 12-point scale on CT. The diagnostic performance of the marked BAC AI score (defined as BAC AI score ≥ 5) for the detection of marked CAC (CAC score ≥ 4) was analyzed in terms of sensitivity, specificity, accuracy and area under the receiver operating characteristic curve (AUC).
Results |
A total of 502 women with a median age of 62 years (age range: 42–96 years) were included. The BAC AI score showed a very strong correlation with the BAC manual score ( r = 0.83). Marked BAC AI score had 32.7 % sensitivity (37/113; 95 % confidence interval [CI]: 24.2–42.2), 96.1 % specificity (374/389; 95 % CI: 93.7–97.8), 71.2 % positive predictive value (37/52; 95 % CI: 56.9–82.9), 83.1 % negative predictive value (374/450; 95 % CI: 79.3–86.5), and 81.9 % accuracy (411/502; 95 % CI: 78.2–85.1) for the diagnosis of marked CAC. The AUC of the marked BAC AI score for the diagnosis of marked CAC was 0.64 (95 % CI: 0.60–0.69).
Conclusion |
The automated BAC AI score shows a very strong correlation with manual BAC scoring in this external validation cohort. The automated BAC AI score may be a useful tool to promote the integration of BAC into mammography reports and to improve awareness of a woman's cardiovascular risk status.
