Aims and objectives

Decrease in muscle mass (sarcopenia), and an increase in subcutaneous and intermuscular (“myosteatosis”) adipose tissue, are both linked to age-, cancer, and chronic disease-related changes.

Hand-held 2D SoS-US is a novel technique, which uses a conventional ultrasound system to measure SoS in tissue. A passive reflector is positioned in opposite of a hand-held ultrasound probe with the tissue in between. The reflector is used a reference to measure the time of propagation of the ultrasound echoes transmitted through the tissue and reflected back to the ultrasound probe.

To assess sarcopenia of calf muscles with a novel handheld ultrasound technique measuring speed of sound (SoS) for quantification of muscle and fat content.
