Sarcopenia has emerged as a significant prognostic factor in liver disease, posing a significant risk to patients in terms of morbidity and mortality. However, the evaluation of skeletal muscle mass and quality remains challenging, as cross-sectional imaging is not a suitable screening tool. In order to better include this crucial variable in the routine risk stratification of patients with chronic liver disease, there is an urgent need for simple and reliable non-invasive diagnostic tools for sarcopenia. Therefore, the use of ultrasound techniques has garnered attention as a promising alternative for detecting sarcopenia and muscle abnormalities. This narrative review aims to provide an overview of the current literature on the use of ultrasound as a diagnostic tool for sarcopenia, with particular focus on patients with cirrhosis, emphasizing its potential limitations and future prospects.
