Synopsis

Keywords: Muscle, Quantitative ImagingIt is well established in literature that MRI quantitative parameters such as T₂ or diffusion coefficients change significantly immediately after a strenuous exercise session. In this work, we instead focus on the long-term effects of regular repeated physical activity on three cohorts characterized by different training regimes. A multiparametric protocol was developed to assess T₁, T₂, fat fraction, and IVIM diffusion values to examine differences in lumbar spine muscle physiology between the different cohorts.
