From: Predicting mammographic density with linear ultrasound transducers
Example of ultrasound images for one patient with low mammographic density (a, b) and one patient with high mammographic density (c, d). Dotted lines refer to the pectoralis muscle. Colored markings indicate areas with high breast density. For better visualization, the Madena software was used. a The original ultrasound image of the left breast, upper outer quadrant for a patient with low breast density, indicated by only small colored areas in b. c The original ultrasound image of the left breast, upper outer quadrant for a patient with high breast density indicated by larger colored areas in d
