Illustration of fatty infiltration across cohorts. Peripheral quantitative computed tomography images illustrating the amount of fatty infiltration into calf muscles in spinal cord injury (SCI) adults compared with younger and older normal adults. For each pair of images—left = native computed tomography scan; right = segmentation of tissues using watershed algorithm. Magenta = subcutaneous fat; blue = muscle; green = bone marrow; and pink = bone.
