Anatomy-Correlated Breast Imaging and Visual Grading Analysis Using Quantitative Transmission Ultrasound™

Figure 7

The transmission (speed of sound) coronal image is able to differentiate between glandular elements (speed values 1517–1567 m/s) from ductal tissue elements (speed values 1560–1612 m/s) in dense breast tissue as shown here in a moderately dense cadaver breast. The “stippled” appearance of the high magnification speed images differentiates the glands (grey) from the ductal and connective tissue elements.
