Which tissue has a speed around 1,700 m/s?

Explanation:
The speed of sound in tissue depends on how stiff the tissue is and how dense it is. Tendon is a very stiff, collagen-rich tissue, so ultrasound waves move through it faster than through most other soft tissues. Its acoustic velocity sits around 1,700 m/s, which is higher than muscle or blood but lower than bone. Bone is much faster, typically several thousand meters per second, due to its greater stiffness and density. Therefore, tendon best matches the around 1,700 m/s value.
