Quantitative measurement of breast density is important for personalized risk assessment and frequent, longitudinal monitoring of breast density modifying drugs. Current standard of care for assessing breast density is qualitative assessment of mammogram, which involves ionizing radiation and breast compression. MRI-derived breast density (MagDensity) using fat-water decomposition has the potential to provide a sensitive and useful tool for clinicians. This study aims to prospectively determine the reliability and reproducibility of this measure across different vendors, scanner models and field strengths
