Goutallier classification (GC) for paraspinal musculature (PSM). Representative axial T1-weighted fast spin-echo (FSE) images for the different GC scores: 0—normal muscle (a); 1—some fatty streaks (b); 2—less than 50% fatty muscle atrophy (c); 3—50% fatty muscle atrophy (d); and 4—greater than 50% fatty muscle atrophy (e).
