Muscle signal changes in muscle fibers, adaptive or by overload, in the recovery from distal myoconnective injury of the femoral biceps and the rectus femoris. a Axial and sagittal fluid-sensitive images show areas of hyperintensity of muscle fibers adjacent to scar in the form of feathery peritendinous interstitial edema (arrows) suggesting overload. b Axial fluid-sensitive image shows area of slightly hyperintensity of muscle fibers adjacent to scar in the form of cotton-like edema pattern (DOMS, dashed circle) suggesting adaptation
