Color-coded maps as a tool to visually detect muscle disease and extreme muscle morphometry. Color-coded maps were obtained based on the myofibers’ cross-sectional area (from ≤ 1000 to > 4000 μm2). Scale bar represents 500 μm. Representative images of deltoid muscle from patients diagnosed with a dermatomyositis, b anti-synthetase myopathy, c necrotizing autoimmune myopathy, d neurogenic atrophy, and e type II atrophy with angulated fibers. f Patient showing a large fiber size phenotype. Characteristics of these patients are described in Table 5. Left: original immunofluorescence-stained section. Right: color-coded image. MyHC, myosin heavy chain
