- Sarcopenia, generally known as severe muscle wasting, has been redefined as a more complex syndrome related to muscle mass and strength. It can be present in patients of all body types (underweight, overweight, obese). - Sarcopenia can be established from calculation of skeletal muscle cross-sectional area. This can be done using image analysis software and single cross-sectional images from routine CT and MR examinations. This measurement has been shown to correlate with whole-body skeletal muscle mass and is now the gold standard for diagnosing sarcopenia. - Literature review has shown that sarcopenia can be a predictor of clinical outcome, including increased length of hospital stay, nosocomial infections, overall decreased survival and higher incidence of dose limiting toxicity during chemotherapy. - As part of a multidisciplinary team, radiologists could help to identify patients with sarcopenia who may benefit from earlier and more aggressive intervention in order to improve their clinical outcomes.
