本文比较了肌肉 CT、活检和肌电图(EMG)对神经肌肉疾病(neuromuscular diseases,NMI))的辅助诊断价值。方法患者53例,男33、女20例。肌病34例,神经元病19例。全部病例均行肌活检组织学和组织化学染色检查。EMG 检查用同心针形电极记录去神经征和募集形式,并测正中、桡、腓神经传导速度。肌肉CT(第二代)从大腿近端1/3到小腿远端1/3作平扫。结果①神经元病组:EMG 和肌活检100%与临床诊断一致;而 CT 只有63%(12/19例)符合诊断。
This article compares the diagnostic value of muscle CT, biopsy and electromyography (EMG) to neuromuscular diseases (NMI). Methods 53 cases of patients, 33 males and 20 females. Myopathy in 34 cases, 19 cases of neuronal disease. All cases were performed muscle biopsy and histochemical staining. EMG examination using concentric needle electrode recording denervation and recruitment of forms, and to correct, radial, peroneal nerve conduction velocity. Muscle CT (second generation) from the proximal thigh 1/3 to the distal one-third of the leg for plain scan. Results ① Neuron disease group: EMG and muscle biopsy 100% consistent with clinical diagnosis; CT only 63% (12/19 cases) in line with the diagnosis.
