An experimental model of contusion injury in humans
Fig 1
MRI image, at 24 h post-impact, of oedema in the quadriceps after impact with 7.2 kg.
Oedema is identified as regions of high intensity and area measured (highlighted area) so that oedema volume could be quantified. Additionally, fat (b) and muscle thickness (c) were measured at the site of impact. (a) denotes the vitamin E capsule marker placed on the centre of impact. Axial T2-weighted TSE SPAIR FS (TR 4160 ms; TE 61 ms; FOV 230 × 230 mm; slice thickness 4 mm; interslice gap 0 mm) was used for imaging.
