Muscle Multi-parametric NMR Imaging Development in Aged People With Sarcopenia or Frailty Syndrome; CLINical Study

Frailty is a multideterminant syndrome in which muscle function appears to play a central role. Muscle function depends on brain control, nutrition and perfusion. We hypothesized that multiparametric MRI assessment combined with comprehensive gerontological assessment (CGA) and routine biological assessment of inflammation in a sample of older people with and without diabetes will allow to explore on one side the possibilities of multi-parametric MRI muscle and brain imaging to describe the correlates of frailty and on the other side will describe the different muscle/brain alterations due to diabetes in frailty. The main objective is to compare the lipid percent of the rectus femoris in frail and pre-frail older subjects and in non-frail older subjects.
