A new deep-learning model accurately detects, segments, and quantifies breast arterial calcifications on mammography, aiding both cancer and cardiovascular risk screening.
Key Details
- 1The DL model uses a modified U-Net architecture tailored for BAC segmentation and quantification.
- 2In testing with mammograms from 369 women, the model achieved Dice scores of 0.90 (training) and 0.89 (validation) for segmentation.
- 3Classification accuracy for BAC detection was high, with F1 scores of 0.97 (validation) and 0.93 (training).
- 4Bland-Altman analysis validated the model's reliability for calcium quantification, with a mean difference of -0.98 mg in the training set.
- 5Manual annotation by seven radiologists enabled categorization into six BAC mass levels.
- 6The approach could transform mammography into a dual-purpose screening tool for breast cancer and cardiovascular disease risk.
