Sarcopenia in type 2 diabetes mellitus: an imaging review

Sarcopenia is characterized by an age-related decline in muscle mass, strength, or endurance. It is increasingly prevalent in patients with type 2 diabetes mellitus (T2DM) and is now regarded as a key complication of the disease. Additionally, it has a significant impact on patients' prognosis. Imaging methods are crucial tools for assessing muscle mass and microchanges. Moreover, they can facilitate the early diagnosis of sarcopenia. Thus, this article reviews the pathological basis and clinical manifestations of sarcopenia in T2DM, the advantages and disadvantages of imaging assessment methods, their specific applications, imaging manifestations, and research progress.
