Decreased quadriceps muscle stiffness on ultrasound elastography is associated with sarcopenia in end-stage kidney disease

Sonoelastography provides a reliable and non-invasive assessment of quadriceps muscle stiffness and demonstrates good predictive value for detecting sarcopenia in ESKD patients. Given its accessibility, low cost, and ease of use, sonoelastography may serve as a valuable adjunct to conventional DXA in evaluating muscle quality in this high-risk population.
