对145例神经肌肉疾病的CT扫描结果表明：肌源性和神经源性的诊断是不一致的，不能认为是绝对的。在肌源性疾病中，在保留肌肉轮廓的情况下，肌肉的X射线密度早期降低。在神经源性疾病中，肌肉体积早期减少。肌肉萎缩和肥大共存主要提示肌肉疾病。一些卷入的模式似乎是频繁的。在Duchenne营养不良症中，在活动期萎缩的“空肌”或肥大的肌肉与在终末期的“幽灵”肌肉之间存在对比。在面肩臂肌营养不良症中，胫前肌和腿筋肌密度通常降低，腰大肌正常或肥大。在强直性肌营养不良症中，常可见腹侧低密度的新月体。肢体带状肌病(保留界限的“空”肌、肥大的肌肉、低密度的腓肠肌)和慢性脊髓性肌萎缩(无选择性受累的不规则萎缩的肌肉和肥大的肌肉)之间的诊断是暂定的，但不被认为是明确的。肌肉受累在肌萎缩侧索硬化症中分布不对称，而在周围神经病中则相当对称。
CT Scan examination in 145 cases of neuromuscular diseases yielded the following results: Diagnosis between myogenic and neurogenic process is inconstant and cannot be considered as absolute. In myogenic diseases the X ray density of muscle is early decreased with a preservation of muscle outline. In neurogenic diseases muscle volume is early decreased. Coexistence of atrophic and hypertrophic muscles indicates primarily muscle disease. Some patterns of involvement appear to be frequent. In Duchenne's dystrophy a contrast exists between atrophic "empty" or hypertrophic muscles during the ambulatory period and "ghostly" muscles during the terminal period. In facio-scapulo-humeral muscular dystrophy, tibialis anterior and hamstring muscles have often a decreased density and psoas muscles are normal or hypertrophic. In myotonic dystrophy a hypodense perifemoral crescent is frequently observed. Diagnosis between limb-girdle myopathy ("empty" muscles with preserved limits, hypertrophic muscles, hypodense gastrocnemius medialis muscles) and chronic spinal amyotrophy (irregular and atrophic muscles without selective involvement and hypertrophic muscles) is tentatively proposed but is not considered to be clear-cut. Muscle involvement has an asymmetric distribution in amyotrophic lateral sclerosis and is rather symmetric in peripheral neuropathies.
