In this preliminary observation study, the investigators will assess muscle function in terms of muscle strength and leverage imaging (MRI) and spectroscopy (31P-MRS) based techniques to assess longitudinal changes in muscle volume, quality and metabolic function in patients with T2D and obesity prescribed to semaglutide therapy. The patients will be evaluated at three time points: 1) baseline, 2) 3-month and 3) 6-month after the therapy. These longitudinal changes will then be compared and correlated with changes in physical measurements such as BMI and patient reported outcome measures (PROMs). The primary aim of our study is to investigate the longitudinal effects of semaglutide therapy on patients with T2D and obesity, on skeletal muscle strength, muscle volume, quality and metabolic function.
