Progress in the application of ultrasound in the diagnosis of sarcopenia
Sarcopenia is a progressive loss of skeletal muscle mass associated with aging,which significantly increases the risk of falls,disability,and mortality in the elderly.The loss of muscle mass serves as a critical indicator for diagnosing sarcopenia.Ultrasound,characterized by its cost-effectiveness,portability,non-radiative nature,and repeatability,plays a vital role in assessing muscle mass.This article will review the value of ultrasound in the diagnosis of sarcopenia and explore the application of new techniques.
