A novel quantification method for automatic computation of breast density from mammography images using deep learning
This study introduces a fully automated deep-learning pipeline for quantifying mammographic dense rate (MDR) and characterizes age-related MDR trajectories in a large-scale screening cohort. The AI model, built with a U-Net segmentation network, was trained and validated on a dataset of mediolateral-oblique images with manual annotations for pectoral muscle, glandular, and fatty tissue. The segmentation model achieved a DICE coefficient of 0.967. Applied to 240,465 MLO images from 134,411 women aged 40–79, the mean MDR was 31.7±25.9%, declining steeply from early 40s to late 50s, then plateauing. Longitudinal analysis revealed two distinct patterns: a rapidly decreasing group and a persistently high-density group. This vendor-agnostic pipeline enables accurate, standardized MDR measurement, eliminating observer variability, and supports quantitative MDR as a practical tool for risk-adapted breast-cancer screening and personalized adjunct imaging modalities.

Case Study: Age-Related MDR Trajectories
This study revealed two distinct age-related MDR patterns crucial for personalized screening: a rapidly decreasing group and a persistently high-density group. Understanding these trajectories is vital for tailoring breast cancer screening strategies.
Case 1: Rapid MDR Decline
A patient experienced a sharp drop in MDR from age 40 to 50, with mammograms showing increasingly fatty breast tissue. For such individuals, AI-driven MDR tracking can predict when their density will fall below clinically relevant thresholds, potentially allowing for adjusted screening intervals or modalities.
Case 2: Persistently High-Density & Tumor Marker
Another patient diagnosed with non-invasive ductal carcinoma at age 67 showed no significant MDR change until age 63, after which MDR began a gradual rise. This demonstrates that continuous MDR monitoring can serve as a valuable tumor-marker, suggesting that an increased MDR, even at older ages, may precede cancer diagnosis and warrants further investigation.
Impact: By identifying these distinct groups, AI-driven MDR quantification supports dynamic, risk-adapted screening protocols. Patients with persistently high density can be prioritized for adjunct imaging (e.g., ultrasound, MRI), while those with declining density might follow modified surveillance plans, optimizing resource allocation and improving early detection for all.
