神经肌病四肢肌萎缩的CT表现

The CT Manifestation of the Limbs' Muscular Atrophy in Neuromuscular Diseases

笔者报告了１１例正常者和３９例神经肌病患者四肢肌肉的ＣＴ表现。除了肌肉密度有不同程度的降低、萎缩及真、假性肥大外，各肌肉之间的间隔在各种肌病中也有不同程度的增宽，借助ＣＴ的测量作为定量分析的依据，可帮助我们进一步鉴别神经原性及肌原性肌萎缩，特别是不同肌萎缩的早期鉴别诊断。

The CT manifestation of limbs'muscles in 11 normal controls and 39 patients with nuromuscular disease were reported mainly.Apart from the decreasing density,atrophy and pseudohypertrophy of muscles,there is the increasing of muscular intervals in muscular diseases.By CT quantitative assessment,we can differentiate between neurogenic and myogenic muscular atrophy,especialy in early stage.
