Assessment of diffusion tensor imaging indices in calf muscles following postural change from standing to supine position

Object To investigate whether postural change from erect to recumbent position affects calf muscle water diffusivity.Materials and methodsTen healthy adults (27.2 ± 4.9 years, 3 females) were imaged at baseline (following assumption of recumbent position), and after 34 min (session 2) and 64 min (session 3) of laying supine within a 3T MRI scanner. Diffusion tensor imaging (DTI) eigenvalues, fractional anisotropy (FA) and apparent diffusion …
